Expand functools features to methods, classmethods, staticmethods and even for (unofficial) hybrid methods.
For now, methodtools only provides methodtools.lru_cache.
Use methodtools module instead of functools module. Than it will work as you expected.
from methodtools import lru_cache class A(object): # cached method. the storage lifetime follows `self` object @lru_cache() def cached_method(self, args): ... # cached classmethod. the storage lifetime follows `A` class @lru_cache() # the order is important! @classmethod # always lru_cache on top of classmethod def cached_classmethod(self, args): ... # cached staticmethod. the storage lifetime follows `A` class @lru_cache() # the order is important! @staticmethod # always lru_cache on top of staticmethod def cached_staticmethod(self, args): ... @lru_cache() # just same as functools.lru_cache def cached_function(): ...
PyPI is the recommended way.
$ pip install methodtools

If you are working on Python 2, install also functools32.
