inheritance

[yag]

Hello,

I am new to python (or to any programming language). My first post on this list,
so please go easy. Apologies if its a FAQ.

Here is what I have

--------------------------------
#! /usr/bin/env python3
# -*- coding: utf-8 -*-

class A(object):
    def __init__(self, a):
        print('a = ', a)
        self.a = a

    def foo(self):
        print('printing from foo in A = ',self.a)

class B(A):
    def __init__(self, b, a):
        super(B, self).__init__(a)
        print('b = ', b)
        self.b = b

    def foo(self):
        print('printing from foo in B = ',self.b)

class C(B):
    def __init__(self, c, b, a):
        super(C, self).__init__(b, a)
        print('c = ', c)
        self.c = c

    def foo(self):
        print('printing from foo in C = ',self.c)

x = C(3,2,1)
x.foo()
--------------------------------

three classes A,B,C and instance x.

now how can I call methods foo in class A and B using 'x' instance. (I hope I
could pronounce the terminology correct)

Thanks.
