Question

I\'m using @functools.lru_cache in Python 3.3. I would like to save the cache to a file, in order to restore it when the program will be restarted. How could I

Answer 1

You can use a library of mine, mezmorize

import random
from mezmorize import Cache

cache = Cache(CACHE_TYPE='filesystem', CACHE_DIR='cache')


@cache.memoize()
def add(a, b):
    return a + b + random.randrange(0, 1000)

>>> add(2, 5)
727
>>> add(2, 5)
727
