Without a sample of your code and the actual tracebacks you're getting
it is difficult to know what's going wrong.


Are you writing your class like this:

class Character:
    def __init__(self):
        # do some stuff here..

class Marine(Character):
    def __init__(self):
        Character.__init__(self)
        # do some stuff here..

?
