If there's a chance you might have multiple inheritance at some point in
this hierarchy, you might also try using super:
class cl1(object): # note it's a new-style class
def __init__(self):
self.a = 1
class cl2(cl1):
def __init__(self):
super(cl2, self).__init__()
self.b = 2
Note that you probably want a new-style class even if you chose not to
use super in favor of Jp Calderone's suggestion. There are very few
cases for using old-style classes these days.
