  • A template inheritance system like the concept of object-oriented programming.
  • Caching framework that can use a wide variety of cache types.
  • An internal dispatch system that allows parts of the application to communicate with each other via predefined signals.
  • Internationalization policy, including translating Django’s own elements into different languages
  • Django Model is a serialization system that can create and read XML and/or JSON representations of events.
  • A system that extends the capabilities of the template engine.
  • Good Interface to Python’s built-in unit testing framework.
  • Django REST Framework is a powerful toolkit that can be used for building web APIs.
