Introduction to Django:

Django, pronounced as [`d], is an open source web development framework written in Python and follows the design of MVC. Lawrence Publishing Group developed this framework to develop a news-based website, which was released under the BSD license in July 2005. The name comes from the Belgian jazz musician DjangoReinhardt, who is a gypsy who mainly plays guitar and violin. Due to the rapid development of Django in recent years, it is more and more widely used. It is selected as 2013SDTimes100 by the famous IT development magazine SDTimes, ranking sixth in the category of "API, Library and Framework", and is considered to be a leader in this field.

The main purpose of Django is to develop database-driven websites easily and quickly. It emphasizes code reuse, multiple components can easily serve the entire framework in the form of "plug-ins", Django has many powerful third-party plug-ins, and you can even easily develop your own toolkit. This makes Django very scalable. It also emphasizes the principle of rapid development.
