Python: Print string representing of time from a tuple

Python Operating System Services: Exercise-26 with Solution

Write a Python program that takes a tuple containing 9 elements corresponding to structure time as an argument and returns a string representing it.

Sample Solution:

Python Code :

import time
t = (2020, 1, 22, 2, 34, 6, 6, 362, 0)
result = time.asctime(t)
print("Result:", result)
t = (1982, 11, 12, 2, 54, 8, 8, 360, 0)
result = time.asctime(t)
print("Result:", result)

Sample Output:

Result: Sun Jan 22 02:34:06 2020
Result: Tue Nov 12 02:54:08 1982

Python: Cache results with decorators

There is a great way to cache functions with decorators in Python. Caching will help save time and precious resources when there is an expensive function at hand.

Implementation is easy, just import lru_cache from functools library and decorate your function using @lru_cache.

from functools import lru_cache

@lru_cache(maxsize=None)
def fibo(a):
    if a <= 1:
        return a
    else:
        return fibo(a-1) + fibo(a-2)

for i in range(20):
    print(fibo(i), end="|")

print("\n\n", fibo.cache_info())

Output:

0|1|1|2|3|5|8|13|21|34|55|89|144|233|377|610|987|1597|2584|4181|

 CacheInfo(hits=36, misses=20, maxsize=None, currsize=20)
