Using cachetools as a convenient short-hand to use Python functiion caching for a specific argument

cachetools-example.py

from cachetools import cached
from cachetools.keys import hashkey

from random import randint

@cached(cache={}, key=lambda db_handle, query: hashkey(query))
@cached(cache={}, key=lambda db_handle, query: hashkey(query))
def find_object(db_handle, query):
    saved = query
    query = 5
    print("processing {0}".format(query))
    query = saved
    return query

queries = list(range(5))
queries.extend(range(5))
for q in queries:
    print("result: {0}".format(find_object(randint(0, 1000), q)))
