Python inheritance: TypeError: object.__init__() takes no parameters

You are calling the wrong class name in your super() call:

class SimpleHelloWorld(IRCReplyModule):

     def __init__(self):
            #super(IRCReplyModule,self).__init__('hello world')
            super(SimpleHelloWorld,self).__init__('hello world')

Essentially what you are resolving to is the __init__ of the object base class which takes no params.

Its a bit redundant, I know, to have to specify the class that you are already inside of, which is why in python3 you can just do: super().__init__()
