Get class that defined method in Python

Question

How can I get the class that defined a method in Python?

I'd want the following example to print "__main__.FooClass":

class FooClass:
    def foo_method(self):
        print "foo"

class BarClass(FooClass):
    pass

bar = BarClass()
print get_class_that_defined_method(bar.foo_method)

Answer 1

import inspect

def get_class_that_defined_method(meth):
  obj = meth.im_self
  for cls in inspect.getmro(meth.im_class):
    if meth.__name__ in cls.__dict__: return cls
  return None

Answer 2

What's wrong with

bar.__class__

?

That's the class that defines all methods of object bar.
