In today’s world, Python is one of the most widely used languages. The guy who created this language is Guido Van Rossum. Python 0.9.0 was released in 1991. It’s a dynamically typed, interpreted, object-oriented language that makes writing code simple and logical. Python has libraries and frameworks for almost every technical domain imaginable.
Moreover, there are several robust Python compilers and IDEs that make development with the popular programming language easy and efficient. The Python programming language offers a wide range of applications in terms of implementation.
Because web development is one of the major applications of Python, it’s critical to know which Python framework will best fit your needs. Before we go into discussing the best Python frameworks and how they are used, let’s first know what a framework is.
What is a Python Framework?
A framework consists of a number of modules or packages. Using Python frameworks reduces development time by providing a prebuilt implementation of redundant tasks. This means that developers don’t have to worry about common aspects like protocols, sockets, and so on, and can instead focus on developing application logic.
Python frameworks simplify the execution of typical solutions, allowing users to concentrate on the application logic rather than the basic routine activities. Each framework has its own set of advantages and disadvantages, therefore the framework that is chosen is entirely dependent on the project needs as well as the preferences of the developer or development team.
Frameworks have a few key advantages: they are open-source, safe, well-documented, and efficient. The following are some of the features found in web framework-based applications:
- Form Handling and Validation: A webpage’s most frequent operation is to take user input in a form and then execute validations on it.
- ORM Support: Applications developed using frameworks allow database connection using ORM.
- Output Formats with a Template Engine: A template engine enables programmers to create desired content types such as HTML, XML, and JSON.
- Security: Framework-based apps provide web security.
- Session Storage Management: Apps developed using frameworks offer the feature of session storage and retrieval. This means once the page session is over, all the data stored in session storage gets deleted.
- URL Routing: Routing is the process of directly connecting a URL to the code that makes a web page.
Why Use Python Frameworks?
The flexibility of a framework over a library is its primary benefit. They’re extensible, and they give us the tools we need to expand their capabilities. While using a library one must understand how to use each feature in order to execute specific tasks.
However, because of the systematic control of the flow, frameworks make it quite simple. All we have to do now is guide our operations by utilizing one of the framework’s features.
Also, Python frameworks enable code reuse for basic HTTP activities much easier. They organize the projects in such a way that other developers who are familiar with the framework may easily maintain and develop the program. In the next section, we will see different types of Python frameworks.
Types of Python Framework
Python frameworks come in a trio of flavors. Full-stack frameworks, micro frameworks, and asynchronous frameworks are the three main categories of frameworks available in Python. Let’s have a look at what each of these categories has to offer:
- Full-Stack Framework: This type of Python framework, as the name implies, offers a complete web development solution, including form generators, form validation, and template layouts, among other things. Any application can benefit from this framework.
- Micro Framework: It’s a simple, lightweight framework with no additional functionality such as a data abstraction layer or form validation. To gain extra features and functionalities, developers must spend a significant amount of time manually writing code. For small applications, this is really beneficial.
- Asynchronous Framework: This framework has recently gained popularity, and it works with the asyncio library. This type of Python framework is mostly used to handle large numbers of concurrent connections.
Best Python Frameworks
In this section, we will look into some of the top python frameworks available in the market starting with the de facto best Python framework Django:
1) Django
Developer – Adrian Holovaty and Simon Willison (original), Django Software Foundation (present)

Django is a full-stack Python framework that comes with all of the functionality you’ll need out of the box. It is a free and open-source framework. It adheres to the DRY concept, which stands for “Don’t Repeat Yourself.”
Django’s ORM mappers are used to connect objects to a database. An ORM, or object-relational mapper, is a code library that uses the object-oriented paradigm to enable you to manage data from a database. Django uses PostgreSQL, MySQL, SQLite, and Oracle as its primary databases. It can also use third-party drivers to connect to other databases.
Key Features of Django
- It uses the URL Routing feature.
- The Python framework supports authentication.
- Django has a functionality that allows you to migrate your database structure.
- The most crucial aspect of this Python framework is security. Django is more secure than other leading Python frameworks.
