The Programming Language Ranking of 2020 confirms that Python has officially outranked Java, making it the second most popular web development language. The 2020 Developer Survey reveals that Python is the first most wanted and third most loved programming language. As of March 2021, Python still ranks at the top position in the PYPL Popularity Report.

What makes it such a popular and reliable programming language?

It’s the simplicity, versatility, easy syntax, and phenomenal developmental capacity that make it superior. Today, Python is the top priority for the majority of programmers and tech service providers. To make the leading programming language more user-friendly, many frameworks have been introduced.

These frameworks automate the implementation process, power redundant tasks, and improve developmental time. It also allows the developers to emphasize more on the logic of the application.

There are many different Python frameworks popular among web developers. Based on the unique types of frameworks, we are going to discuss the top ones you need to learn in 2021.

Types of Python Framework

There are three types of Python frameworks, popular among web developers and programmers.

  • Full-Stack Framework

These frameworks are a single solution for all of the developmental needs. They come pre-packaged with all the essentials required to build a phenomenal app. It has MVC architecture, ORM technique, routers, templating engine, etc. all in the same place. These frameworks are typically used for bigger enterprise-level projects.

  • Microframework

A lightweight framework that offers only essential things necessary for app development with minimal coding. They lack features such as form validation, database abstraction layer, etc., and other functionalities. However, microframework can be extended with the databases on demand. You can easily scale them to a full-stack solution.

  • Asynchronous Framework

An asynchronous framework is like a microframework extended version that can handle a larger set of concurrent connections. Using this framework, you don’t need to execute your tasks consequently. Instead, you can run another task before the completion of the previous one. They use the programming language’s asyncio library.
