identifying new not inherited methods

I am writing a library in which I need to find the names of methods
which are implemented in a class, rather than inherited from another
class. To explain more, and to find if there is another way of doing
it, here is what I want to do: I am defining two classes, say A and B,

class A(object):
    def list_cmds(self):
        'implementation needed'
    def __init__(self):
    ... (rest of class)

class B(A):
    def cmd1(self, args):
    def cmd2(self, args):

I need an implementation of list_cmds in A above so that I can get a

>>> b=B()
>>> b.list_cmds()
['cmd1','cmd2']                    #order not important

I will be happy if anybody can point to me any way of doing it, using
class attributes, metaclasses or otherwise. What I don't want to do is
modifying class B, which contains just the cmds, if possible.

Many thanks in advance.
