Analyzing Django

What is Django?

Django is a high-level, open-source web framework created in Python, supported in 2005 and planned by Adrian Holovaty for building web applications quickly and efficiently. It follows the MVC (Model-View-Controller) architectural pattern, commonly referred to as MV in Django. Django provides structured foundation for developers to create web applications by emphasizing reusability, rapid development, and the ‘Don’t Repeat Yourself’ (DRY) principle. 

Simply, and as stated on the Django website, it is the web framework for perfectionists with deadlines.

5 Django Key Features
