Top 14 Python Frameworks in 2022

Python is one of the most popular programming languages in the world today. Its open-source code, powerful development libraries and object-oriented programming style render it an ever favorable option for developers.

Not only its immaculate build but the relevant ease with which it can be learned by even beginners make it an indomitable programming language at present.

Web development, building software, data analysis and visualization are some of the routine tasks generally operated in python.

Web Framework

Web framework refers to all the overhead processes involved while creating a new web application. It lays a standardized procedure for developing and deploying these applications on the internet.

This may include libraries, template processors and session managers. Python frameworks can either be full-stack or non-full-stack depending on the size of your project.

The majority of Web frameworks are exclusively server-side technology, although, with the increased prevalence of AJAX, some Web frameworks are beginning to include AJAX code that helps developers with the particularly tricky task of programming (client-side) the user's browser. At the extreme end of the client-side Web Frameworks is technology that can use the web browser as a full-blown application execution environment.

Winding Up

Alas,  we have come to the end of the list for best python frameworks available out in the market. Choosing the right framework is critical to the app’s success. There are still many more frameworks out there, or even being made when I ’am writing this blog.

For new developers, Flask can be a great option. It is relatively easy to use, with lesser coding at the same time delivers optimum performance.

Among microframeworks, CherryPy and Bottle are consistently ranked best for their amazing performance when it comes to building small-scale applications. Not only that, scalability is a prominent feature in these frameworks.

Django is the best in the market, any day if you ask me. Compared to the little learning curve it has, this framework has some extraordinary features as add-ons, you can learn them along with your web development as and when needed. Third-party additions are favorable to modify any framework to fit into your applications and Django can adapt such third-party drivers.

If you are only starting out and are confused about what to choose, I'd suggest you make use of this list and analyze their features thoroughly so that you get the right fit for your application.
