Web development is the umbrella term for conceptualizing, creating, deploying and operating web applications and application programming interfaces for the Web.

Python can be used to build server-side web applications. While a web framework is not required to build web apps, it’s rare that developers would not use existing open source libraries to speed up their progress in getting their application working.

Python is not used in a web browser. The language executed in browsers such as Chrome, Firefox and Internet Explorer is JavaScript. Projects such as pyjs can compile from Python to JavaScript. However, most Python developers write their web applications using a combination of Python and JavaScript. Python is executed on the server side while JavaScript is downloaded to the client and run by the web browser.


Some of the top companies use Python in their technology stacks:

  • Instagram — a social media platform that relies on Python to allow its 4 mil daily active users to photograph, edit, store, and share their creations in a person digital album.
  • Spotify — a major market player and a music streaming app that incorporates data analytics to manage its Radio and Discover features.
  • Disqus — this commenting plugin processes around 50 mil comment per month, and it is available in 19 countries.

There are several factors that simplify the use of Python for web development:

  • Low entry barrier
    Python is similar to the English language we use in everyday life. The simplicity of the syntax allows you to deal with intricate systems and ensure that all the elements have a clear relationship with each other. Thanks to this, more newbie coders can learn the language and join the programming community faster.
  • Good visualizations
    Representing data in a format that can be easily understood is achieved using different plots and charts. They are an efficient way to visually present and comprehend data. Web development companies utilize Python libraries (e.g., Matplotlib) that make it possible to visualize data and create clear and easy-to-understand reports.


Fewer Seasoned Developers

When you need to have an app created for you, you certainly want the most experienced developers to do the job. However, it’s not so simple with Python, since not many expert programmers are working with this language, especially when you compare it to Java.

Lack of True Multiprocessor Support

Multiprocessing is an important part of writing an application. Python does support multiprocessing, although it might not be as flexible or convenient as other languages. This can create certain limitations when you’re writing the code.

Speed Limitations

Python is often criticized for its speed. It is an interpreted script language, which makes it relatively slower than a lot of its compiled counterparts, such as C/C++ or Java, due to the different methods it uses to translate code. Yet, some Python benchmarks work faster than those of C and C++.

That being said, Python is not the only one with potential speed problems. Ruby, Perl, and even JavaScript are on the slower end of the scale as well.
