A question about inheritance

[arserlom at gmail.com]

Hello I have a question about inheritance in Python. I'd like to do
something like this:

 class cl1:
  def __init__(self):
   self.a = 1

 class cl2(cl1):
  def __init__(self):
   self.b = 2

But in such a way that cl2 instances have atributes 'b' AND 'a'.
Obviously, this is not the way of doing it, because the __init__
definition in cl2 overrides cl1's __init__.

Is there a 'pythonic' way of achieving this?
