python app development frameworks

The latest Statista research shows that over 48% of developers worldwide use Python for software development. Python is among the most popular programming languages, with major firms like IBM, NASA, Spotify, and Instagram using them. Many developers use PyJNIus Python frameworks for App Development that are designed to provide the interaction between Python and Android API.

The popularity of Python is because of its vast range of libraries, packages, and frameworks. A Python application 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.

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.

Why Should I Go for Python App Development?

Python is best suited for creating dynamic applications integrated with CRUD operations and avoiding repetitive coding for activities like authentication and sessions. It also provides an execution system when you’re building a separate UI with associated logic. 

Python is also the best option when you have strict deadlines and time and resource constraints. From full-stack and DevOps to AI/ML, data engineering, and data science, Python offers all-around development options. 

Here are some reasons why Python is the king of programming languages:

  • Python’s vibrant range of frameworks, libraries, and tools enables swift development and gives access to code templates.
  • Python is a high-level programming language and quite close to English, hence it has a lower learning curve compared to other coding languages.
  • Python has a large developer community and rich documentation with new frameworks and libraries being added quite often.

Types of Python App Development Frameworks?

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

1-Micro Framework

Micro Framework

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 Framework

Full-Stack Framework

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 Framework

Asynchronous Framework

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.

How to Choose the Right Python Framework For App Development?

The most essential factor before selecting the right framework for development is the nature, size, and complexity of the project. For example, you can opt for a micro-framework for a smaller project while considering full-stack frameworks for larger projects. 

Also, here are some examples of frameworks based on the project’s nature.

Python application development

Other factors that you can consider before selecting a Python app development framework for your project are

  • Scalability to handle traffic load when they run on several servers
  • Core libraries like authentication, data validation, URL mapping/rewriting, and templating.
  • Comprehensive documentation with tutorials, sample codes, blogs, and snippets.
  • Easy installation of the preferred Python framework.

10 Most Popular Python App Development Frameworks

Here’s a list of the most popular python app development frameworks:
