It might be better to use newstyle classes if you can. Also, the
convention is to use CamelCase for classes names (unless you have a
strong reason to do otherwise).

Here you could use a class attribute to provide a default:
class Creature(object):
noise = ""
def voice(self):
return "voice:" + self.noise
class Dog(Creature):
noise="bark"
def voice(self):
print "brace your self:"
return Creature.voice(self)
# can also use this instead, cf the Fine Manual
return super(Dog, self).voice()
My 2 cents
