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.
