I've got an inheritance question and was hoping brighter minds could
guide me. I am in the strange situation where some of the methods in a
subclass are actually more general than methods in a superclass. What
is the preferred way to handle such situations. My original thought was
to do something like this:
class AA(object):
def general_method(): pass
class A(AA):
# redefine general_method() to call a
# restricted version of AA.general_method()
class B(A,AA):
# redefine general_method() to call AA.general_method()
This seems ugly to me, and I am wondering if there is a better method.
So any suggestions would be appreciated.
Thanks!

For a more "concrete" example:
Suppose all the animals in the world have only 1 or 2 legs.
class Legs(object)
def run(): pass
def walk(number_of_legs):
# lots of commands
# that do not depend on the
# number of legs but definitely
# have to do with walking
if number_of_legs == '1':
# blah blah
if number_of_legs == '2':
# blah blah
# more commands
class HasAtLeastOneLeg(Legs):
def walk():
# Legs.walk(number_of_legs=1)
class HasTwoLegs(HasAtLeastOneLeg,Legs):
def walk()
# Legs.walk(number_of_legs=2)
# isinstance(HasTwoLegs, HasAtLeastOneLeg) --> True
