Django: The Web framework for perfectionists with deadlines

Django is a high-level web framework that encourages rapid development and clean, pragmatic design. Built by experienced developers and maintained by the non-profit Django Software Foundation (DSF). it takes care of much of the hassle of Web development, so you can focus on writing your app without needing to reinvent the wheel. It’s free and open source.

Django follows the (model-view-controller) architectural pattern. This consists of:

  • an object-relational mapper that mediates between data models
    (Python classes) and a relational database ("Model")

  • a system for processing requests with a web templating system ("View")

  • a regular-expression-based URL dispatcher ("Controller")

The team prefers to think of Django as an "MTV" framework, where 'M' is the model, 'T' is the template and 'V' is view.

In , 'views' describe which data are presented while 'templates' describe how that data is presented.
