Delegates in python

Question

I\'ve implemented this short example to try to demonstrate a simple delegation pattern. My question is. Does this look like I\'ve understood delegation right?

Answer 1

That's the basic concept, yes - passing on some incoming request to another object to take care of.

Answer 2

One Python tip: you don't need to say:

func = getattr(self.handler, 'Handle')
func(event)

just say:

self.handler.Handle(event)

I'm not sure what you are doing with your Handler class, it isn't used in your example.

And in Python, methods with upper-case names are very very unusual, usually a result of porting some existing API with names like that.
