Even this won't be enough if the class has inherited methods from
superclasses, though.  For that situation, you'll need something like this
(almost untested):

def classdir(c):
    res = dir(c)
    try:
        for s in c.__bases__:
	    res += classdir(s)
    except AttributeError:
        pass
    return res

It is far from perfect, but should illustrate the principle...

Finally, this would do what you (might) want (almost untested too):

import types
def superdir(obj):
    if isinstance(obj, types.InstanceType):
        return dir(obj) + classdir(obj.__class__)
    elif isinstance(obj, types.ClassType):
        return classdir(obj)
    else:
        return dir(obj)

Peace,
