Choosing Between Python Web Frameworks

Posted by

Python is the fastest growing programming language. There are good reasons for this growth, including high salaries (an average per annum salary of $114,490 per annum, according to Indeed), excellent job demand and the sheer number of exciting innovations that rely on Python such as machine learning, artificial intelligence (AI), big data, robotics and cyber security. “If you decide you want to build a web application, and you would like to develop it in Python, you’ll probably want (to use a) web framework,” explains Gareth Dwyer, software and operations developer at HyperionDev. So which Python web framework should you choose?

Frameworks: What Do They Do?

Frameworks are there to make your life easier. According to Coding Dojo, a framework is a collection, or library, of packages or modules that helps you build web applications that are scalable, reliable and maintainable. Frameworks make it possible for you to reuse code for common procedures or operations. They are really a repository of work compiled by previous programmers. Frameworks let you skip over the low-level details including protocols, sockets or process/thread management.

If you’re a developer, you’re generally going to write code that allows you to ‘plug in’ to the framework, explains the Python website. You’ll cut development time by automating the implementation of common solutions, so that you can focus on the logic of your application. And the good news with Python is that you’re spoilt for choice when it comes to frameworks including Django, Flask, Pyramid, Tornado, Bottle, Diesel, Pecan and Falcon. This piece will focus on Django and Flask, which are likely the two most popular Python web frameworks.

Some Things To Consider When Deciding On A Framework

When deciding on which Python web framework to choose, here are some factors worth considering:

  • How big and complex is your project? A full-stack framework – e.g. Django –  might be a better option if you’re wanting to develop a large system with features and requirements, but these frameworks come with limitations. A microframework might be better for a smaller project.
  • How much external support are you going to need? Django, for example, has 80 000 Stack Overflow questions (and even more answers) as well as a large number of blogs from developers and users, whereas other communities aren’t as big.

Some Common Python Web Frameworks

1. Django

2. Flask

Gareth Dwyer, who is also the author of Flask By Example, summarises it as follows:

‘You should probably choose:

  • Django, if you’re focused on the final product. Especially if you’re working on a straightforward application such as a news site, an e-store, or blog, and you want there to always be a single, obvious way of doing things.’
  • Flask, if you’re focused on the experience and learning opportunities, or if you want more control about which components to use (such as what databases you want to use and how you want to interact with them).’

In conclusion, it’s clear that a Python framework can be invaluable when it comes to developing web applications. Whether you choose Django or Flask depends on the complexity of your project and the degree of flexibility you require.
