8 best Python frameworks for web development

Python frameworks for web development are the things that make developers’ lives easier. They enable developers to focus mainly on the app’s logic instead of wasting time on implementing routine and redundant tasks. 

Python developers use the most prominent programming language. Thus they can benefit from a wide variety of frameworks of different types, choosing by their advantages and functionality. Check below the kinds of Python frameworks and our selection of the best Python frameworks for web development based on our long-term professional experience.

Python Frameworks Types

1. Full-Stack 

The extensive feature set of this kind of framework can usually meet all developer requirements and serve well for a project of any complexity. 

2. Microframework

The lightweight frameworks offer a primary batch of features without additional tools and libraries. It is supposed that a lot of code and additional requirements will be added by the developer. 

3. Asynchronous 

Frameworks of this type can handle multiple connections simultaneously, making them more and more popular.
