Avoid specifying all arguments in a subclass

Question

I have a class:

class A(object):
    def __init__(self,a,b,c,d,e,f,g,...........,x,y,z)
        #do some init stuff

And I have a subclass w

Answer 1

Are you wanting something like this?

class A(object):
    def __init__(self, a, b, c, d, e, f, g):
        # do stuff
        print a, d, g

class B(A):
    def __init__(self, *args):
        args = list(args)
        self.__W = args.pop()
        A.__init__(self, *args)
