You normally need to call the superclasses' __init__ method as well.
Example:

    def __init__(self):
        Pykkar.__init__(self)
        ... any of your own init stuff ...

Likewise for your world_l class.

BTW, it is conventional to start class names with an upper case letters. Just
style, but it helps other people when reading your code.
