Top 20 Python Frameworks for Web Development in 2021

Python frameworks help to automatically reduce the development time of the developer and automate the redundant project. The best part is that Python allows a wider range of frameworks where every framework has its own benefits as per the varied needs of a project. Python is a general-purpose, high-level programming language for desktop GUI applications, websites, and web applications. Besides, it being a high-level programming language enables you to concentrate on the core functionality of the application by dealing with joint programming tasks.

It is a daunting job to select the best match for your project. Here comes the simple, flexible, high-level programming language(Python) at the top of the popularity list to our rescue, which has several python frameworks to support web applications of different sizes. Python frameworks are a set of web software modules or packages that automatically implement common solutions to concentrate on the application logic rather than on the basic processes.

Going forward, let us start discussing the top Python Frameworks for Web Development in 2021:

Types of Python frameworks

Before diving straight into the Python frameworks for web development, Let us first discuss the 3 primary types of python frameworks that exist-

1. Full-Stack Framework
2. Micro Framework
3. Asynchronous Framework

Let’s understand what each of these entails-

Full-Stack Framework

It offers the basic component structure for various web solutions- i.e. frontend, backend, and database. If we want to build a wide system that can be loaded with lots of features, a full-stack framework comes in handy.

Micro Framework

A micro-framework is an extremely lightweight framework with no additional features or functions available. Micro-frameworks work best if you need to add huge quantities of code and additional specifications manually.

Asynchronous Framework

It is a micro-framework that allows us to mainly manage a vast range of concurrent links. It is primarily built for Python and it utilizes the Asyncio library.
