Django is a Python web framework that encourages rapid development and clean, pragmatic design. It uses the MTV (Model Template View) pattern rather than MVC. Django features an ORM, form handling, template system and admin interface. To set up a Django project, you create a project directory, install Django, add apps, set up models and URLs, and develop templates and views. Django promotes loose coupling, DRY principles and writing minimal code.
