使@lru_cache忽略某些函数参数

使@lru_cache忽略某些函数参数

使用cachetools可以编写：

from cachetools import cachedfrom cachetools.keys import hashkeyfrom random import randint@cached(cache={}, key=lambda db_handle, query: hashkey(query))def find_object(db_handle, query):    print("processing {0}".format(query))    return queryqueries = list(range(5))queries.extend(range(5))for q in queries:    print("result: {0}".format(find_object(randint(0, 1000), q)))
