No, a classmethod is passed the class that it is called on. If you have an inheritance tree you don't know this with a staticmethod. >>> class Test(object): ... @staticmethod ... def static(): # no args ... print 'I have no clue how I was called' ... @classmethod ... def cls(cls): ... print 'I was called on class', cls ... >>> t=Test() >>> t.static() I have no clue how I was called >>> t.cls() I was called on class <class '__main__.Test'> >>> >>> class T2(Test): ... pass ... >>> t2=T2() >>> t2.static() I have no clue how I was called >>> t2.cls() I was called on class <class '__main__.T2'> >>> T2.cls() I was called on class <class '__main__.T2'> I can't think of a good use case for this at the moment...maybe some factory functions might care...
