I suggest a built-in function "methods()" that works like this:
def methods(obj):
if type(obj) is InstanceType: return methods(obj.__class__)
results = []
if hasattr(obj, '__bases__'):
for base in obj.__bases__:
results.extend(methods(base))
results.extend(
filter(lambda k, o=obj: type(getattr(o, k)) in
[MethodType, BuiltinMethodType], dir(obj)))
return unique(results)
def unique(seq):
dict = {}
for item in seq: dict[item] = 1
results = dict.keys()
results.sort()
return results

Happiness comes more from loving than being loved; and often when our
affection seems wounded it is is only our vanity bleeding. To love, and
to be hurt often, and to love again--this is the brave and happy life.
