Calling base class method in Python

Question

I have two classes A and B and A is base class of B.

I read that all methods in Python are virtual.

So how do I call a method of the base because when I try to call it, the method of the derived class is called as expected?

>>> class A(object):     def print_it(self):         print 'A'   >>> class B(A):     def print_it(self):         print 'B'   >>> x = B() >>> x.print_it() B >>> x.A ??? 

Answer 1

Using super:

>>> class A(object): ...     def print_it(self): ...             print 'A' ...  >>> class B(A): ...     def print_it(self): ...             print 'B' ...  >>> x = B() >>> x.print_it()                # calls derived class method as expected B >>> super(B, x).print_it()      # calls base class method A
