Python has become one of the most used programming languages with 28 % of the market share. Large corporations like Google and Netflix use the reliability and efficiency of its framework for web development.
Although Python offers several advantages, it does not include certain intrinsic options that enable the generation of complex web applications on the fly. To solve this, the developers employ the utilization of elaborate frameworks that manage the specifics of execution and intuitively ease the process of development. The current guide explores the top Python web frameworks to use for web development in the year 2024.
Python web framework is a set of packages or modules designed to allow a programmer to design web applications or services with as much abstraction as possible from low-level details like protocols, sockets, or process/thread creation. These frameworks help with:
Request filtering
Generating responses
Storing data persistently
Now, let us look into several Python web frameworks that are the most practical and famous.
Django is among the Python Web Frameworks. Django is an ISO fork-free Python web Application Framework that is acclaimed for the fast creation of complex codes and applications. Primarily, it is applied to build APIs and web apps as it now comprises approximately 12000 projects. That explains why Django is considered popular with its great libraries, less code to be written, and reusability of components.

Specifies URLs that applications should use
Integrated authentication system
Effective URL scheme
The language used in databases about object-oriented programming language.
Customizable admin interface
Supports multiple cache mechanisms
Limitations:
Slightly less suitable for small-scale projects and undergraduate levels as it is a high-level architecture.
This can cause a slow website depending on the number of requests
Does not have coding conventions like that of Rails.
It is one instrument that demands a profound understanding for proper application.
CherryPy is a Python-based, lightweight, fast, and very stable web application framework. It is open-source and can be used while developing any frame of a Python-supported project.
