Best Python Frameworks To Explore in 2024

Python is one of the most popular and widely used programming languages, with 28% of market share. Its ease, simple English-like syntax, and powerful tools and Python frameworks make it even more preferable. 51% of developers choose Python for varied development projects.

Another reason for its increasing popularity is its extensive toolset, libraries, and frameworks that made integrating the latest technologies like AI, ML, IoT, and others easier. If you have a good grasp of the Python framework, you can easily build any application.

To make it even easier for you to start a Python application development journey, we have listed the top 13 frameworks to learn in 2024.

Why Choose Python?

Python is a rising and demanding technology of the decade. Its simple rules, flexibility, and support for building user interfaces make it attractive to many programmers. Many companies, like Netflix, Instagram, and Dropbox, choose Python for their work. These sites handle millions of user requests every day, and Python helps them run smoothly.

• As per the Popularity of Programming Language Index, the demand for Python has risen by 8.7% in the last 5 years. 
• With a 20.17% rating, Python stands at first position as per Tiobe.

What is a Software Framework? 

These frameworks are sets of tools and programs that help developers build and manage software more easily. They handle common tasks like working with databases, managing URLs, and user logins. This lets developers focus on the specific parts of their projects.

The framework helps developers ensure best practices that save their development time and effort in building something from scratch. Using frameworks will also reduce code errors and past mistakes, improving code. In this blog, we will discuss top Python frameworks.

8 Reasons to Use Python Frameworks for App Development

Developing software from scratch is complex and time-consuming. Frameworks help make this process easier. They provide a structured way to build and manage your code, which keeps things organized and supports your development efforts.  

Here’s why using a framework is beneficial.

1- Saves Time: Frameworks help speed up development. They handle common tasks like error handling and data management, so developers spend less time on these details.

2- Organizes Development: Frameworks keep your code and files neatly arranged. They manage things like interface files and directories, letting developers focus on building features.

3- Enhances Security: Good frameworks offer strong security, protecting your code from potential attacks, especially in web applications.

4- Community Support: Many frameworks are open-source and have large communities. These communities provide help, resources, and solutions to common problems.

5- Simplifies CRUD Operations: Frameworks make it easy to Create, Read, Update, and Delete data. They also simplify tasks like session management and database access.

6- Boosts Productivity: Developers can use frameworks to build faster prototypes, app deployment, and code reuse. It improves the overall developer’s productivity so they can focus on more logic rather than fixing code.

7- Supports Teamwork: if you have a large team working together in a hybrid model, then using a framework will help you collaborate better in real-time. Everyone can contribute to the code altogether without impacting the process.

8- Python for mobile applications: With the availability of several frameworks, you can easily build mobile apps.

Using frameworks in python not only helps developers but also helps businesses improve their time-to-market and build solid and successful projects with less scope for error. 

You must schedule a call with experts to understand how to create an app using Python.

Python Software Framework vs Library

Python offers libraries and frameworks to ease the development process. But what is the difference between a library and a framework?

You must understand this for a better choice.

Library: A library is like a set of pre-made tools that you can use in your program. It helps you with specific tasks, like handling data or creating charts. You pick which tools to use and how to use them.

Framework: A framework is like a detailed guide or plan for building an entire application. It gives you a structure to follow and includes built-in features to help you along the way. It helps you set up your project and gives you a lot of support as you build it.

3 Main Types of Python Frameworks

 Python frameworks fall into three main types:

1. Full Stack Frameworks

A full-stack framework is a complete solution for all your development needs. It helps build and manage both the client-side and server-side of applications. It’s also known as an enterprise framework because it handles everything related to development. Examples: Django, Web2Py, Pyramid.

• These frameworks will help you manage both the front-end and back-end with one framework without switching between different parts of the app for Python.
• Suitable for small and medium-sized businesses because they only need one full-stack developer.
• Scalable and can be upgraded easily.

2. Microframeworks

A microframework is a lightweight tool for app development with specific features. It’s often used alongside a full-stack framework to build an application. Examples: Bottle, Flask, Falcon.

• Ideal for small projects with specific needs.
• Easy for beginners to learn and use.
• Flexible and adaptable.

However, you cannot use Microframeworks for features like form validation, database handling, or user authentication.

3. Asynchronous Frameworks

Asynchronous frameworks are used for applications that need to handle many tasks at once. They work independently from the main application threads and are useful for large, complex networks. Examples: AIOHTTP, Sanic, FastAPI.

• Improve performance and speed of applications.
• Help organize code well and are easy for teams to use.
