    Python is one of the most popular languages in the programming industry. It is a high-level interpreted programming language that follows the concepts of object-oriented programming. The availability of a myriad of robust libraries and frameworks is one of the main reasons for the extensive popularity of Python among the computer science community. If you compare Python with other programming languages, you will find that it is the most straightforward language of all. The simple syntax of Python makes it a preferable choice among programmers. Also, it supports several libraries and frameworks that allow programmers to code fast and develop projects in less time. This blog post aims to make you familiar with the most popular Python frameworks that you can use to speed up the development process and make yourself more efficient. But before we list down the best Python frameworks, let us briefly introduce you to web frameworks, Python web frameworks, and types of Python web frameworks.

    What are Web Frameworks?

    There are lots of definitions available on the internet about a web framework, but most of them are confusing because they use jargon or technical terms. This could make it difficult for a beginner to understand what actually a web framework is. In simple terms, a web framework is defined as a collection of libraries (predefined code) and APIs (Application Program Interfaces) that call a piece of code to perform a specific task. Web frameworks are built on specific programming languages. Therefore, instead of writing code from scratch to create a web application, we use web frameworks. There are many popular frameworks in the market, such as Laravel (PHP framework), Spring ( Java Web-Framework) , Ruby-on-Rails (Ruby framework), and Django (Python Framework).

    Python Web Frameworks

    Python is well known for its robust web frameworks. It offers many frameworks that can meet the requirements of your projects. Whether you want to make a simple blog application or a complex eCommerce website, there are various Python frameworks to help you develop projects quickly and with relative ease. If you are thinking of learning a Python framework in 2022, we have provided the best ones to choose from.

    Types of Python Web Frameworks

    1. Full-Stack Python Web Frameworks

    A full-stack web framework is a framework that supports the development of front-end interfaces, back-end services, and databases. These frameworks work on architectures like Model View Controller (MVC) or Model View Template (MVT) and use Object Relational Mapping (ORM) for Databases. Here, the developer does not need to depend on other libraries and frameworks.

    2. Non-Full Stack Python Web Frameworks

    In non-full stack frameworks, the developer does not find many auxiliary features like that in full-stack frameworks. Here, the framework depends on other libraries for complete functionality.

    Python Frameworks Type
    Django Full Stack
    Pyramid Full Stack
    TurboGears Full Stack
    Web2py Full Stack
    CubicWeb Full Stack
    Flask Micro-web framework
    Bottle Micro-web framework
    CherryPy Non-Full Stack
    Sanic Non-Full Stack
    Tornado Non-Full Stack

    Best Python Web Frameworks

    1. Django

    https://www.youtube.com/watch?v=rHux0gMZ3Eg Django is the most powerful and popular Python framework. With more than 53k stars on GitHub, Django is the second most starred framework. It is built on Python and comes with many built-in features. Django is a full-stack framework that supports built-in authentication and all the popular SQL databases. Using this framework, we can create dynamic, powerful, and secure web applications. URL routing, user authentication, templating, and inbuilt database support are the main features of Django. It was first released in 2005, and since then, it has been an open-source project. In the past few years, due to the popularity of Python, developers started showing interest in Django. Object-Relational Mapping (ORM) is another key feature of Django. With this feature, we can store and retrieve application data from different SQL databases, such as MySQL, Oracle, SQLite, and PostgreSQL. With Django, we can build any web application, small or big. However, Django is primarily recommended for big projects. Although the learning curve of Django is quite steep, its official documentation makes it easy to get started with Django.

    Important Features

    • ORM (Object-Relation Mapper).
    • Tight integration between components.
    • Automatic admin interface.
