Function Caching in Python

 

import time

from functools import lru_cache

@lru_cache(maxsize=5) #It will reduce the time size of the function

def some(n):

    time.sleep(n)

    return n

if __name__ == '__main__':

    t1 = time.time()

    some(4)

    print("Om")

    some(4)

    print("ok")

    t2 = time.time()

    print(t2-t1)
