python frequently asked questions

If you are a student looking to hone your Python development skills or a software professional attending an interview for the role of a Python developer, the following are the most commonly asked technical questions along with answers on Python web development. Simply scan through these questions for you to assess your knowledge about Python and you are all set to impress your examiner or the interview panel.

This question bank, with $$$$ questionsand answers on Python web development, will come as a quick reference guide for all the software developers and students looking to gain proficiency with the various facets of Python. For your benefit, all the questions are in bold.

Here are some of the topmost questions that can be posed as the initiating part of an interview can be:

Q1.What is Python? Can you enlist the benefits of using Python?

Python is a high-level, general-purpose programming language that comes with web frameworks. These web frameworks consist of modules (packages) which are used by developers to write and build web applications. Flask and Django are some of the prominent frameworks that are employed in the creation of web applications. Python also offers a host of threads, exceptions along with an automatic memory management feature.

The following are the benefits of using Python to develop web applications.

It is very easy to learn Python since it involves writing minimum code scripts. Identified as a beginner-friendly language, Python encourages swift development along with a luxury of a logical and clean web design. It is a free and an open-source language which brings in the features of portability, extendibility and a built-in data structure.

Q2. How can you say that Python is interpreted?

A Python program can be run directly from the source code. The language has a built-in capability to convert the source code that is developed by a programmer into an intermediate language. This code in intermediate language is again translated into a machine language that can be executed to show up desired results.

Q3: Can you describe the process of using Python to develop websites?

Python helps developers build websites in 3 simple steps:

  • Your first step is to learn about Python programming along with its syntax and features. You will also have to gain knowledge about the basics of “http” protocols along with a clear understanding of the manner in which a web server works. You should also be acquainted with the process of exchanging data between server and client.

  • The next step concerns the mastering of Python frameworks like Django and Flask. Delving deep into Django will help you gain knowledge about Model-View-Controller (MVC) design pattern.

  • After gaining proficiency with the first two steps, your last step that makes your dream to build a website come true is to extend efforts towards making your website publicly available. You should check out multiple web hosting options and pick up the best which allows your app to run on it. Some of the web hosting services that you can rely on are RedhatOpenshift, Google App Engine, BigRock, Heroku and AWS.

Now, let’s move on to some coding questions that can be posed as part of your examination or technical interview for the role of a Python Web Developer.

Q4: Can you write a function that helps you randomize the items of a “List-in-Place”?

Python comes with an in-built <random> module. This can be used to export a public method <shuffle(<list>)> which can randomize any sequence that you input. Below is the code that enables the <random> function.

import random


print”Prior Shuffling – 0″, list


print”After Shuffling – 1″, list


print”After Shuffling – 2″, list

Q5: Can you bring out the difference between Java and Python with regard to Exception Handling? Additionally, can you list the optional clauses for a <Try-Except> Block in Python?

Python implements Exceptional Handling in a different way when compared to Java. Python offers an option to use the <try-except> block which allows the developer to view the error details without stalling the execution of the program. And the best part of this <try-except> block is that programmers who get to identify the problem can also come up with a solution to the error. Below are the two clauses that are available with Python with regard to Exceptional Handling.

  • try-except-finally
  • try-except-else

Q6: What is the best way to transform a Python string into a list?

Python offers strings which are very similar to lists. If you want to convert a string into a list, you simply need to pass the string as an argument to the list. And the output you get by following this simple rule comes in the form of a string which is converted into a list.

list(“I am learning Python.”)

This is how the output looks like:


[GCC 4.8.2] on linux

=>[‘I’,’ ‘,’a’,’m’,’ ‘,’l’,’e’,’a’,’r’,’n’,’i’,’n’,’g’,’ ‘,’P’,’y’,’t’,’h’,’o’,’n’,’.’]

Q7: Can be talk about the built-in types that Python provides?

Python offers a set of mutable and immutable built-in types.

Mutable built-in types include:

  • Dictionaries
  • Lists
  • Sets

Immutable built-in types are:

  • Numbers
  • Tuples
  • Strings

Q8: How are the different methods to copy an Object in Python?

Typically, Python allows us to use <copy.copy()> or <copy.deepcopy()> to initiate copy operations on Objects. However, you should keep in mind that all the objects do not support these methods but most of them do.

Yet, some objects can be copied easily, like the dictionary objects, using <copy()> method.

Here is an example that explains this method:

item={n: n*2for n in range(10)}



Q9:What is the code that can help you determine the name of an Object in Python?

In Python programming language, there are no objects that can be represented with names. Hence, you cannot associate a name with an object. However, you can assign a value that can be linked to its name. You can then employ the name to exclusively access the value. At the most, Python allows you to locate the reference name of the object.



:def __init__(self, name):


self.name = name

def __str__(self):

return'{} holds …’.format(self.name)

obj1 =Test(‘obj1’)

print obj1

obj2 =Test(‘obj2’)

print obj2

Q10: What is the code to check whether a particular object belong to a Class or a Subclass? 

Through Python, developers can make a list of instances of an object that can be linked to many classes. Python offers an in-built mechanism that permits the above feature. This method results in the form of a table comprising of tuples instead of individual classes. Below is the syntax for the same:

<isinstance(obj, (class1, class2, …))>

It is through the above code that you as a Python developer can check the presence of an object in any one of the classes. <isinstance(obj, str)> or <isinstance(obj, (int, long, float, complex))>are a couple of in-built types which manifest in the form of many formats representing the same function.

However, it is important to use built-in classes. You can instead create a user-defined class.

The underlying example helps you determine the object of a particular class:




print”Look for a mailbox”


print”Look for a document”


print”Unidentified object”

Q11: Can you explain the significance of namespace in Python?

In Python, it is possible to assign a place for every name. This place allows the name to be hooked to its location. This, in Python, is known as namespace. Presented in the form of a box, it is here that the variable name is mapped to the object that is placed. Whenever a code is written to search for a particular variable, the object will be retrieved by searching the box.

Q12: How do you convert a number to a string, using Python?

Developers use the inbuilt function str() to convert a number into a string. In the event programmers want to come up with an octal or hexadecimal representation, Python allows them to use the inbuilt functions like hex() and oct().

Q13: Can you define a module and package, in Python?

A module as per Python demonstrates a way to structure a program. Every Python program file is hence a module which does the job of importing other modules like attributes and objects.

A package of modules is denoted by a folder, in Python. Thus, a package in Python can have multiple modules and subfolders.


The above explained question and answers regarding Python web development can handhold both experienced and beginner-level programmers to ace in an interview or an exam. Just scan through this question bank consisting of 13 FAQs on Python and you are all set to impress the interview panel or the examiner who is evaluating your answer script.

hire prestashop expert

Prestashop is a versatile platform that lets developers customize the online shops of their clients according to their needs, preferences, and products.

It has got thousands of modules that help in enhancing the functionality of Prestashop. But to reap the benefits of it, you need to hire the services of an expert. Every web developer is not an expert in Prestashop. Let us go through some points that you should remember before hiring a Prestashop expert.

  1. Expert in PHP

Prestashop uses object oriented PHP as its programming language. The prestashop expert needs to be skilled at PHP to modify the modules in Prestashop and overriding the cores files. So good knowledge in PHP coding is an essential prerequisite for a Prestashop expert. You must enquire about his or her PHP certificate and work experience.

  1. Company vs Freelancer

Many people make a blunder in choosing this. There are many freelancers in the market that claim to be an expert in PrestaShop. But having many dawbacks of hiring a freelancer, it is advisable you opt for a company or a team.

  1. Expert in object oriented programming

Object oriented programming is the mainstay of Prestashop. So the expert in Prestashop needs to be familiar with object oriented programming. Otherwise, he will not be able to write unique modules for your online shop. So you need to enquire about his experience in object oriented programming.

The person also needs to have good knowledge about writing SQL queries. This is because the data for your Prestashop-developed online shop will be stored in MySQL database. So knowledge of SQL is a must for the developer.

  1. Look out for communication

Communication has always been a key factor in any ecommerce website. Hence, the same applies to PrestaShop experts too.  Check for the communication factors while interviewing a prestashop expert. Note down how long they take to repond to your quesries and calls.

  1. Embedding PHP in HTML code

Prestashop uses a template called Smarty which uses a unique, but simple syntax that helps designers embed PHP in HTML code. However, simple it may be the developer needs to have complete knowledge of it before starting to develop new modules. In other words, he must be experienced enough. An experienced developer will definitely have knowledge about the syntax of smarty. So, ask the developer about his experience.

  1. Mockups is a must

Module development is a specialty in Prestashop. The expert needs to develop a module that best suits the requirements of your service, product or nature of supply. Do insist on your expert to provide you with the mockups so that you have a clear understanding about how the design and development will be carried out. The developer needs to have good coding experience since he needs to code to design new modules that will add some unique functionality to Prestashop.

  1. Experience in implementing overriding

The process of Overriding is something unique about Prestashop. If the developer is an expert in overriding classes, then he will be able to replace parts of the core code with his or her unique code. He would not even touch the core code and yet change the function to something useful and unique to your online shop.

  1. Hosting on apache server

The expert, you are hiring as Prestashop expert, needs to have the experience of hosting websites on apache server. Prestashop e-commerce websites need to be hosted on Apache 2X web server though it also works with Apache 1.3. So the developer needs to have some experience of hosting websites on Apache server.


All in all, don’t forget to check the background and profile of the expert you are willing to hire. This will allow you to understand the various projects were done and research about it.There are many cases of fraud individuals who boast about their achievements. So make sure you through their profile well before hiring them,

SSL certification is the ultimate concept that attracts buyers to use their credit or debit cards to conduct purchase online. So apart from everything else the developer or the expert should have some expertise or some experience in implementing SSL certifications.

Languages for IOT Development

Internet of things is a concept which binds “Things” together making objects even smarter. However, it is clear on how strongly it’s going to impact in the routine life of people.

But if you take a look at the demand for the Internet of Things(IoT), you will realize that it is so much into reality with connected cars, smart thermostats and even the home hubs such as Python, Multiple languages and Node.js to name a few.

So most of you are still curious to know what kind of coding is involved and how does it look like. Ideally, the reason behind its efficient functioning is the use of same languages which are similar to the one that we use on our personal computers and mobile devices.

Other than C, Java, JavaScript, and Python there are many other languages as well which are ruling nowadays. However, when it comes to making a choice amongst it, you are of course likely to get confused. Let’s have a look.


The most popular language, JavaScript, is known for its features in event-driven applications used for all sorts of web browsers. The event-driven applications allow devices to communicate which each other based on events generated by a user.  It can last a long in the market since it makes the devices interoperable and can work well on hubs and servers to gather the data.


This one is another trending one which is mostly used for small applications. But the best part is you can use this language for different platforms with the help of an Embedded Virtual Machine (EVM) which supports B#.


This one is the most common language that is used for creating the iOS apps. To handle the libraries and build up the best infrastructure, such type of source is used by many IoT developers.


For coding, Java is considered as the best source and no doubt is chosen by many developers for IoT development. It has derived its methods from coding languages like Mesa, C++ and many more, which makes it more powerful.

The developers can create and debug the programs on their desktop to later transfer it to a chip which also makes the language a preferred one.


Shares applications that are more similar to C. it is one embed language which was introduced by Google. The best part about it is that it’s more powerful than C language which allows the devices to work in a cordial way by which you can send and receive different data simultaneously.


Though it is not so popular on the list certainly it is one of the best options you can come across. If you want to keep your IoT compact then such low-level programming language is best but you are advised not to have more expectations from it.


If you are thinking about PHP then probably, you can think of blogs and website prototypes. Generally, most of the people don’t use it for IoT but if it is used in the stack, it can juggle micro services on the server. Besides, it has also made a lot easy to put a LAMP stack on a chip.


This was one of the preferences by many IoT developers since its main focus was on the web applications and now can also be used as a scripting language which sticks different coding together. Now it has evolved to such an extent that IoT developers use it as a primary source of language.


Just like Google, Mozilla also came up with another interesting open source language which can do some of the marvelous things that are impossible. It helps to share information through different channels automatically


For the IoT applications, this language is the best one to opt for since it supports all the parallel process. It is important for the developers to know the fact that there is a lot of difference between the parallel and concurrent processors. You can see the same use of syntax in languages like Java, C#, and Python.


The final verdict is that every language above has its own benefits and role to play. But this can change over time looking at the rapid pace at which the technology is evolving. So make your smart choice for smart devices.

Python web development

Python is an object-oriented language that has marked its position in the web development industry. This interactive and modular language is dynamic in nature and portable, as well. Its good assistance for reusability mechanisms and its free availability has made it a prime choice for diverse enterprise applications.

In short, the language named after Monty Python is giving a tough competition to its counterparts with lots of improvements on the go.

Its usage is not just limited to one single platform as its excellence can be utilized in a variety of ways. Considering its ease of use and faster to program nature, it is now widely used in a corporate environment too. For many number of reasons, Python is regarded as the industry’s most preferred language. Let’s find out why?

  1. Availability:

    It is one of the best in the open source systems introduced so far. This simply means that the efficient software can be accessed free of cost. Ventures with budget constraints can make use of this free gem to improve the exposure of their online business. And while using CPython, users even have the permission to alter the source code and distribute it.

  2. Easier to Use:

    It is one of the web development languages that are designed with beginners in mind. Not much technical skill or brilliance is needed to understand and use this language and that is why it is renowned as a beginner’s language. As it needs only comparatively fewer programming codes, it becomes easy for new programmers to handle it and it’s easy to debug nature add to the convenience. Despite its white space usage, it is considered more readable compared to any other languages. Moreover, it is fun to use the language with no way of stress.

  3. Stability:

    With new versions, the language keeps on adding improvisations to match with changing needs. This form of stability makes the language easy to handle during any phase of the project. Unlike C-based languages, the language has no pointers. This makes it a safe and reliable option. Also, the errors never go silent making it easy for you to read and understand if the program crashes. This enables you to correct the errors on the go. With minimal characters and more use of plain English language, it is visually uncluttered.

  4. Philosophy:

    The unique philosophy of Python is another key factor that makes it different from the programming languages. The Zen of Python summarizes the language philosophy that emphasizes that “Explicit is better than implicit”, “Readability counts” and a lot more. In fact, Swift, CoffeeScript, Cobra, and Groovy are among the languages that were designed after Python owing to the influence of its philosophy and design.

  5. Easy Integration:

    It can be easily integrated with other popular languages for better results. The third-party modules in Python Package Index (PyPI) are the key assistance for easy collaboration with other platforms. The popular among the integrated languages are CPython (Python with C), Jython (Python with Java), IronPython (.NET and C#), PyObjc (Objective-C toolkits) and RubyPython (Python with Ruby). Its quick transition time to other languages is really impressive and a lot faster that one can imagine.

  6. Versatility:

    Its versatility in use is another important factor for its wide use. The software runs without any obstacles on almost all main operating systems. This includes Linux, Microsoft Windows, and Mac OS X. As object-oriented concept is used, it allows reuse of data structures which in turn minimizes the quantity of repetitive work. In addition to automatic memory management and a dynamic type system, Python runs on multiple programming paradigms.

  7. Learning Curve:

    Compared to other languages, Python has a better learning curve. It’s easy to use syntax is one of the key reasons for its easiness in learning. As it has a good readability and clarity, users find it really easy to understand program codes. It almost resembles the basic “pseudo-code” and that is why even the beginners vote for Python language. In fact, an experienced professional can even pick up the language basics in less than a day.

  8. Multiple Domains:

    Its usage is not restricted to a single domain as it has a wide acceptance in diverse domains. Even when it can be rated high for its web applications, it cannot be ignored for its dominance in language development, operating systems; prototyping and web frameworks. In fact, the mission-critical applications of the world’s largest stock exchange are handled by this language. Its role in diverse computational and scientific sectors and development of mind-blowing games cannot be ignored.

  9. In Built Modules:

    Python comes in built with a wide range of library modules that can handle different programming tasks. The language has over 300 modules making it easy to handle different tasks with ease. With the right usage of tools and libraries, Python serves the role of a general-purpose language. In addition to desktop apps, the language has made a strong foundation in artificial intelligence, data analysis, and backend web development. Good support is offered by the library for internet protocols including e-mail processing, HTML, and XML.

  10. Reduced Development Times:

    The same applications that are developed using Java can be made about five to 10 times faster when using the Python language. Similarly, the development pace is much more impressive when you compare an application that is programmed using C or C++. Also, the use of efficient content management frameworks helps with creation of highly interactive websites in a much quicker way with options for easy modification anytime.

  11. Cost Effective Maintenance:

    The maintenance of software is always a challenging task despite its excellence in functionality. For an enterprise with fewer resources and more work to handle, Python has proved to be a vital choice with increased coder productivity. Apart from free license fees that assure a cost-effective creation, the software also promises a cost-effective maintenance.

  12. Short Programs:

    Python performs an application with fewer lines of code. When considering its main counterpart C++, Python does the job in almost half the lines of code. Importantly, this also supports a lower margin for error. And when considering Java, the job is completed in 3-5 times shorter lines of codes. For its enhanced usability, this open-sourced and flexible language has found great applications in shipbuilding industries and movie animations.

  13. Extensible:

    Along with standard modules, there are options to make the software extensible. The free availability of frameworks, libraries, add-on modules, and tool-kits makes the extension a lot easy for the users. A range of programmable interfaces can be easily added to existing applications. With all these options, programmers can handle the projects better with proper and easy collaboration with researchers, quants, and analysts.

  14. Quick Processing:

    Any sort of applications can be developed in a quicker fashion with Python as it has the freedom to work with other programming frameworks. Its fast processing with high-level data typing is one of the key factors that make it a cost saving and time saving option for the enterprises. Even large systems can be documented in no time and modification of search engines is faster than you think with Python. Moreover, its direct problem solving approach makes the language different from its counterparts.

  15. Wide Support:

    The active support community assures wide support to the language users absolutely free of cost. Even when the support is not official, the active users are always ready to help those in need. For technical help, users can make a visit to Python.org where they can refer tutorials. And the support is extended with mailing lists, diverse websites, and USENET “netnews” groups.

In the IEEE Spectrum ranking for the year for the most popular languages, Python clinched the first position. And most of the schools are considering Python for introductory programming courses. The Popularity of Programming Language (PYPL) ranking based on Google trends has marked Python in the third position. With a growing ecosystem, the language has remained popular ever since it was introduced back in 1991. It can be considered as a glue language that easily links up different segments of a complex solution. Its reliability in use is evident from the fact that its clientele includes many global enterprises such as Nokia, Linux, NASA, JP Morgan, Wikipedia, IBM, YouTube, Mozilla, Weekly News, Bank of America, Google, Ultraseek, Yahoo!, Disney and Yahoo Maps. Python web development is in the mainstream for a pretty long period for its efficiency in handling data-heavy sites.

Python web development

Programming languages and scripting languages are vying with one another for a slice of the scripting environment. Language developers are coming up with new features and APIs to speed up the process of application development. New programmer-friendly features are being added to languages to make application development faster.

Java, one of the most renowned has long been the fore-runner among scripting languages due to its versatility such as cross-platform compatibility (Compiled Java program on platforms that has JVM).

However, Python has launched a serious offense against Java in recent years. In fact, the use of python as a scripting language is increasing by leaps and bounds. In such a scenario it is important for programmers to benchmark the performance of Java against Python or vice versa to get a clear understanding of which language to use.

Let us pit one language against the other in terms of parameters of productivity and see who has the edge in today’s application development scenario.

Static Typing Versus Dynamic Typing

Java is statically typed whereas Python is dynamically typed. The problem with static typing is that all variable names need to be declared along with their types. This is because the Java container holds objects in the generic type. It is also because of this reason that when you would save an object from the Java container, it would not remember its type.

So the variable must be explicitly cast to the desired type. If you assign the wrong type to the certain variable the language will trigger a type exception. In terms of productivity of the application developer, this is a negative aspect.

Python, being a dynamically typed language, has done away with the pitfalls of a statically typed language. The Python containers can hold objects of any kind. So, when you save an object from the container it remembers its type. If you are using Python you need not declare any variable. The assignment statement automatically binds a type to an object, irrespective of its inherent type.

Moreover, if a name is assigned to an object of one type, the same may be assigned to an object of a different type. This makes it easy and fast on the part of programmers to write codes.

Long Codes Versus Short Codes

Codes written in Java are longer whereas Python can express the same in shorter codes. Longer codes not only take more time to write but are also prone to error. The longer the code the more are the chances of bugs. So coding in Python is less time consuming than coding in Java.

Cross-Platform Portability

Java is a clear winner in this aspect. Scripts written in Java in one platform are portable to and compatible with many other platforms. Java code written for Windows is portable for android etc. This is because of the Java virtual machine. You have JVM in a platform and JavaScript will run there.

Python is not a cross-platform language. You cannot port a java code written in windows to any other platform. However, with the help of embedded Python interpreter, you can achieve the same objective as with Java. So with the embedded interpreter, even Python can become a cross-platform language.

Updating and Maintaining Codebase

You need to put in extra time and effort to update and maintain a Java codebase. On the other hand, Python emphasizes on the generation of reusable and readable codes. This saves a lot of time for the developer.


Java is not a compact language because of the longer codes and other problems. But Python is a compact language since codes written in it can be implemented with fewer errors and more agility.


Choosing Python or Java isn’t the biggest decision here. Both carry their benefits and drawbacks. However, for a particular project, one is certainly best than the latter. Most of the time, small and medium projects are better going with Python. However, larger projects need Java.

Most Secure Web Programming Language

At the outset, it must be said that if you are searching for the most secure and yet versatile web programming language, then, weare afraid, there is none. All the languages have some pros and cons that cannot guarantee you a complete security.

Recently, a research by WhiteHat security conducted on vulnerabilities of various web programming languages came up with an intriguing finding. It actually shows that all the web programing languages are vulnerable to different kinds of security breach. It is only the facet of vulnerability that varies among different languages.

So your quest should now narrow down to specific vulnerabilities for each language rather than searching for the best as it won’t lead you anywhere. The million dollar question here is how?

Let’s learn how to rank programming languages in terms of their vulnerability

PHP is vulnerable to a comprehensive list of bugs

PHP: Hypertext Preprocessor, is a server side programming language, among the several other web scripting languages, found in almost all the applications. Having its parent in the C and C++ languages, PHP language is very easy and interesting to many naïve users. It can run on both UNIX and windows. It is known as a very cheap reliable and fast.

The once written PHP code has at least one instance of cross-site scripting vulnerability. SQL injection is found in 56% of apps. In fact, SQL: Injection is one of the most easy-to-exploit vulnerability of a web application.

The problem of directory traversal is found in 67% of apps written in PHP and the problem of code infection is found in 61% of apps written in PHP. Credentials management problem can be very damaging for the reputation of a website, and yet it is found in almost 58% of apps written in PHP. Cryptographic issues are found in 73% of apps developed in PHP and 58% of sites accounted for information leakage.

Classic ASP is not far behind

Classic ASP (Active Server Pages) is a powerful tool used to develop websites since it can be easily modified and requires simple text editor. The language encompasses important functionalities which lacks in PHP.

Though the technology offers simple development, it consists of a few downsides due to its each file containing its own inline code. Classic ASP is also found to be vulnerable to a comprehensive list of bugs such as SQL injection, cross site scripting, information leakage, directory removal, insufficient input validation etc.

ColdFusion is giving jitters to developers

Though the name isn’t the most popular, ColdFusion offers an innovative platform that inculcates powerful tools to develop your web architecture. But many web developers avoid using it due to its complicated architecture which cannot be understood by the web owners.

Cross site scripting, information leakage, SQL injection, directory traversal etc. are some of the biggest issues with ColdFusion. However, Adobe Systems has recently addressed the problem of information leakage through updates for ColdFusion 10 and ColdFusion 11.

.NET is insufficient

Before the invent of programming platforms, the developers has to handle a lot of tasks like memory allocation, garbage collection etc. .Net took away this pain by offering the developers a platform for memory management.

Information leakage, code quality and cryptographic issues, directory traversal, cross site scripting, insufficient input validation are some of the critical issues with .NET. Many a times the language platform turns out a bit expensive.

Java is not all hunky dory

One of the widely used 21st century language, Java is a general purpose, object oriented programming language. People many a times are always confused about the best language to work on. If you would understand the popularity of this language and the features it offers, you would certainly prefer this one. The Java code is extremely flexible and can be reused as required. Hence it is one of the favorites of developers. And above all, it’s an open source and free software.

Code quality, code injection, cryptographic issues, and information leakage, cross site scripting, directory traversal are some of the biggest issues with Java web programing language. Java’s memory management is seen as an expensive affair. Also, lack of templates in java sometimes makes it cumbersome to work with.


What you need to note here is that, every language has its own pros and cons. selecting the right technology depends on the nature and size of the project. One thing is for sure and that is – vulnerabilities like SQL injection and cross site scripting are more prevalent in scripting based applications such as PHP, ColdFusion and ASP. However, most of these languages have had security APIs that have covered at least some of the lapses, if not all of them.

prestashop vs magento

The revenue figures of e-commerce market are off the charts at this juncture of time. People are buying more stuff online than they used to be and their number is increasing exponentially every year.

It is expected that global e-commerce business which is expected to reach $4.479 trillion by the end of 2017 will be around 16% of the total retail sales globally.

E-commerce giant like Amazon, e-bay, and Alibaba already have their foothold in the sector. However, what about small-scale merchants or bigger business groups who wish to start their own online store?

They can rely on e-commerce platforms which offer a wide variety of option for starting their own store.

Prestashop and Magento is one of such open-source platforms and are the most famous at the moment. Even though the target market is different for both of them let’s see which one is the best.



Prestashop is insanely easy to install. An installation assistant will guide the user through the entire process and everything will be over within no time. However, the ease of installation will cost the user command over the website in certain aspects.


In Magento, it’s a bit different. The installation should be directly done on the server of the host. Since the process is a bit tricky and needs expertise, there are hosting companies which offer this service for a certain cost.

Perks of Prestashop

The basic setup is free of cost and as easy as it can get. However, additional features and themes will cost you.

In short, to make use of the full potential of Prestashop as an e-commerce website you need to add extra features, modules, payment methods, themes, and templates etc. All these are downloadable from the Prestashop website.

Prestashop supports 65 languages. However, to avail technical assistance you have to either rely on a well experience Prestashop web development team or have to find the solution in their online forum.

Perks of Magento

Magento is basically suited for bigger online store, the sole reason why they are a bit complicated to install and vivid features they offer.

Magento offers better control over the content inside and supports more than 81 languages.

Its scalable architecture and flexible integration makes it the close competitor of Prestashop.



Both Prestashop and Magento are open source. However, in pricing, they are entirely different. As mentioned above Prestashop is free of cost for the initial setup. Further addition of themes and modules will cost the user. What makes Prestashop stand out in the pricing section is its cost-effectiveness. But, Prestashop free edition is basically designed for small-scale merchants. But for those who are planning to launch a big website they have the enterprise version with much more advanced features.

Building a website in Magento requires expertise of skilled developers. What makes Magento expensive than Prestashop is that it’s heavy and requires a dedicated server to run. However, Magento provides free add-ons than that of Prestashop but comparing it to the installation and maintenance cost it won’t make much of a difference.

A healthy and helping community is essential for any open source platform. The community ensures that stability of the software is maintained so that users can enjoy its function seamlessly.


Prestashop has around 1 million community members and solution for almost all the issues will be available in their forums.


Magento community offers extended support than that of Magento. It is expected that Magento has more than 700,000 community members for assistance.


prestashop vs magento



Prestashop integrates well with Google Analytics and eBay and it also integrates with payment solutions like Paypal, Simplify, and Authorize.net etc. Other commonly used integration of Prestashop includes,  Word Press, SEO expert, Amazon Marketplace, Advanced Search 4, Google Merchant Center, Facebook, Twitter, Google Shopping, Newsletter Pro, Facebook, Pixmania, Bitcoin, Mailchimp, Icecat etc.


Integration of Magento includes, CashOnDelivery, ShipWorks, MageMonkey, MailChimp, Mandrill, osCommerce, Correios, Fontis Australia, BeeTailer, DebitPayment, MigraShop, SOFORT, AddThis, WorldPay, Facebook, Twitter, ePay, Searchanise, GoMage. Open ERP, DHL, Bcash etc.

Special Features

There are certain features of Prestashop which Magento does not have and vice versa.

They are,


  • Cron Job set up for exchange rate automatic update
  • Importing CSV files to the products
  • If a product is disabled it can be re-directed to another one
  • robots.txt and .htaccess files can be created automatically
  • Security of the website can be enhanced with auto password expiration, password encryption, alterable security permissions etc.
  • CSS files can be further reduced to improve the performance of the website


  • Layered navigation which helps in product filtering in the search option itself.
  • Captcha option to enhance security
  • Separate design for categories and products
  • Credit card details can be securely pre-saved for offline payments.



Prestashop has upper hand in this section. There are around 3,500 plus modules available in Prestashop for website enhancement. Prestashop also has a live configurator to change fonts and colour of the website to attract customers.


Magento has fewer modules compared to that of Prestashop. However, that doesn’t implicate that Magento is tough for configuration. But the only issue here is that Magento is a bit technical and users who are not exposed to such technicalities may find it hard to handle.

So who is the best?

Without no doubt, anyone can say that Prestashop is simple and so easy to handle and is perfect for small e-commerce websites. Considering Magento in this option can be confusing and tedious job.

Magento is designed for huge and complicated websites and is extremely flexible and scalable in that aspect.

In short, there is no winner here to choose from these two is entirely up to you and how big you wish your website to be.

  • Backward Compatibility:

    This is one of the key areas that are taken into mind when designing an ERP platform and competitors like SAP have always given importance to backward compatibility in their design. However, this is a drawback when it comes to Odoo as their design lacks this functionality. At times of new version release, user needs to go through the hassles of code and data migration.

  • Bugs:

    Top ERP models boast of the minimal bugs or no bugs at all. They do the resolving process at regular intervals to make this possible. However, Odoo is not so fine tuned in this regard as it is comparatively new in the market. It needs a lot of time to come up with such standards.

Similarly, module system can be treacherous if not synchronized properly in Odoo web development.

  • Documentation:

    The way it is documented is not appreciable like the conventional systems. It results in a lack of organization. The categorization within the documents is not that favourable for business users and developers. As the documentation is different for varying versions, it may take some time to switch between particular documents.

Its highly modular nature has silenced the image of conventional ERP systems. You are just one step behind to achieving productivity, quality and efficiency from a single place. But if you are looking to run large enterprises and have enough money to invest heavily on it, you can go for fully established conventional systems such as SAP. However, the final decision should be based on what your actual business is all about and what you are looking for when choosing an ERP system.
