What library can I use to implement event driven programming in Python?

Question

Maybe something like Django signals that doesn't depend on Django.

Django signals can be used to clear cache on saving a model, I'm trying to do the same.

Answer 1

• eventlet
• Twisted
• Tornado
• gevent (either forked or based on eventlet's design)

Of the four, eventlet is probably the quickest to pick up and easiest to use - you don't have to modify a lot of your code to make it event-based in the model of eventlet. It basically does some wrapping of the built-in libraries of python, and can do some runtime monkey patching of your code to make it event-based.

Answer 2

It looks like you want a library like PyDispatcher for signal registration and dispatching rather than an event-loop for networking.

Answer 3

Twisted is for event-driven networking.
