Question

In Python I need to efficiently and generically test whether an attribute of a class is an instance method. The inputs to the call would be the name of the attribute being checked (a string) and an object.

hasattr returns true regardless of whether the attribute is an instance method or not.

Any suggestions?

For example:

class Test(object):
    testdata = 123

    def testmethod(self):
        pass

test = Test()
print ismethod(test, 'testdata') # Should return false
print ismethod(test, 'testmethod') # Should return true

def hasmethod(obj, name):
    return hasattr(obj, name) and type(getattr(obj, name)) == types.MethodType
