Use Twisted anywhere!
Crochet is an MIT-licensed library that makes it easier to use Twisted from regular blocking code. Some use cases include:
Easily use Twisted from a blocking framework like Django or Flask.
Write a library that provides a blocking API, but uses Twisted for its implementation.
Port blocking code to Twisted more easily, by keeping a backwards compatibility layer.
Allow normal Twisted programs that use threads to interact with Twisted more cleanly from their threaded parts. For example, this can be useful when using Twisted as a WSGI container.
