Sharing useful information! A brief introduction to the three major web frameworks of Python

1. Django

Django is an open source web application framework written in Python. The framework pattern of MTV is adopted, namely model M, template T and view V. It was originally developed to manage some of the news content-based websites of Lawrence Publishing Group, that is, CMS (content management system) software.

2. Flask

Flask is a lightweight web application framework written in Python. Its WSGI toolbox uses Werkzeug and its template engine uses Jinja2. Flask is licensed under BSD.

Flask is also called a microframework because it uses a simple core and uses extensions to add other features. Flask does not have a default database or form validation tool.

Flask is very light and you can develop a simple website at a very low cost. Very suitable for beginners to learn. After learning the Flask framework, you can consider learning the use of plug-ins. For example, use WTForm + Flask-WTForm to validate form data, and use SQLAlchemy + Flask-SQLAlchemy to control your database.

3. Tornado

Tornado is an open source version of web server software. There is a clear difference between Tornado and current mainstream web server frameworks (including most Python frameworks): it is a non-blocking server and is quite fast.

Thanks to its non-blocking approach and use of epoll, Tornado can handle thousands of connections per second, making Tornado an ideal framework for real-time web services.
