find class where method was defined ?

[Simon Burton]

>>>
>>class A(object):

.... def foo(self): pass
....

>>>
>>class B(A):

.... pass
....

>>>
>>b=B()
>>b.foo

<bound method B.foo of <__main__.B object at 0xb7b1924c>>

How can I work out what class b.foo was defined in ?

def methclass(meth) :
cls = meth.im_class
name = meth.im_func.__ name__
meth = getattr(cls,nam e,None)
for cls in cls.mro():
_meth = getattr(cls,nam e,None)
if _meth is not None and _meth==meth:
result = cls
return result

>>methclass(b.f oo)

<class '__main__.A'>


(Turns out equality bypasses the methodwraper trickery.)
