Django 3.0, the newest version of the Python framework that allows fast creation of database-backed websites and web services, now supports Python async, one of the most powerful new features in Python to make websites and network services faster.
Async allows Python programs, especially networking apps, to run more efficiently, but existing applications must be rewritten to use it. Django 3 will only work with Python 3.6 and later versions, the better to work with Python’s async programming features.
