Django Web Framework

From djangoproject.com:

Django is a high-level Python Web framework that encourages rapid development and clean, pragmatic design. Developed and used over two years by a fast-moving online-news operation, Django was designed to handle two challenges: the intensive deadlines of a newsroom and the stringent requirements of the experienced Web developers who wrote it. It lets you build high-performing, elegant Web applications quickly. Django focuses on automating as much as possible.
