Mediator Pattern in Python

  1 class Mediator(object):
  2     def __init__(self):
  3         self.signals = {}
  4         
  5     def signal(self, signal_name, *args, **kw):
  6         for handler in self.signals.get(signal_name, []):
  7             handler(*args, **kw)
  8             
  0     def connect(self, signal_name, receiver):
 10         handlers = self.signals.setdefault(signal_name, [])
 11         handlers.append(receiver)
 12 
 13     def disconnect(self, signal_name, receiver):
 14         handlers[signal_name].remove(receiver)

This class helps promote loose coupling in my games. I imagine that with a few lines from Pygnet, I could probably 'loosely couple' objects over a network. :-)
