Normally you'd want to use functools.wraps; def wrapped(func): @functools.wraps def wrap(*args, **kwargs): ... return wrap def wrapped_again(length): @functools.wraps def something(func): ... return something @wrapped_again(12) @wrapped def class_method(self, **kwargs): .... And then the name is "carried", as with docstrings. If you don't want to do that, you'd need to use introspection of a remarkably hacky sort. If you want that, well, it'll take a mo.
