List of Top 10 Python Frameworks for App Development [2024]

Python is the most popular and high-level, general-purpose programming language and also this language supports multiple programming models, including structured, object-oriented, and functional programming.  Most developers prefer Python Frameworks for app development in 2024.

The developers use Pyjnius. It is a Python library for accessing Java classes. It either starts a new JVM inside the process or retrieves the already surrounding JVM (for example on Android). The latest Statista research shows that over 48% of developers worldwide use Python app development frameworks for software development. 

What is a Python Framework?

A Python framework is a collection of modules and packages that allows developers to build apps through a pre-built implementation of redundant functions. They release developers from minor issues like thread management, sockets, and protocols.

The popularity of Python is because of its vast range of python libraries for mobile app development, packages, and frameworks.

Several best Python frameworks for mobile app development and web app development enable seamless, efficient, and swift application development. We’ve listed the best frameworks in this blog.

Python Framework vs Python Library

In Python development, frameworks and libraries are two different concepts.

Python frameworks are used to build applications, providing a scaffolding that dictates the flow and organization of code. Django and Flask are popular frameworks for web development, offering features like URL routing and database integration out of the box.

In other hand a Python library refers to the reusable functions and classes used to simplify tasks, offering specific functionalities like data manipulation or web scraping. For example, NumPy is a Python library for numerical computations and requests for HTTP requests.

Types of Python Frameworks?

There are three types of Python frameworks: Microframework, Full-stack, and Asynchronous Framework.

1-Micro Frameworks

A Python micro-framework is easy to use with basic capabilities or features required for web development and does not have added functionalities like form validation and data abstraction layers. They are lightweight and useful for building small applications.

Some popular examples of Micro Python frameworks include CherryPy, Bottle, Falcon, and Dash.

2-Full-Stack Python Frameworks

A full-stack framework is an end-to-end solution for web and app development with functionalities like template layouts, form validation, form generator, and so on.

It is the most convenient and popular Python framework since it offers features of back-end functions, front-end interfaces, and databases. 

Some popular examples of Full-stack Python frameworks include Django, Pylons, CubicWeb, and Giotto

3-Asynchronous Python Frameworks

The asynchronous framework empowers developers to work on large amounts of concurrent connections, databases, web servers, connection libraries, high-performance networks, and so on.

It is gaining widespread popularity recently since the development of the Asyncio library.

Some examples of Asynchronous Python frameworks are Tornado, Growler, AIOHTTP, and Sanic.
