Thanks Maric! That's very close to what I want, although using dir()
can be misleading because if you invoke it on class B you get all of
class A's methods as well. I took your idea and wrote it up like
this:
def find_defining_class(obj, meth_name):
"""find and return the class object that will provide
the definition of meth_name (as a string) if it is
invoked on obj.
"""
for ty in type(obj).mro():
if meth_name in ty.__dict__:
return ty
return None
Cheers,
Allen
