How to extend Class instance

Question

MyClass is defined in module.py. There is no way we can modify it. But we do know the Class definition looks like this:

class MyCla         


        

Answer 1

Ended up with this solution till there is better one posted...

class MyClass:
    def method(self, msg):
        print 'from method:', msg

def function(msg, callback):
    print 'from function:', msg
    callback(msg)

foo = MyClass()
foo.function = function
foo.function(msg='message', callback=foo.method)
