Python: Find the epoch is on a given platform
Python Operating System Services: Exercise-19 with Solution
The epoch is the point where the time starts, and is platform dependent. For Unix, the epoch is January 1, 1970, 00:00:00 (UTC). Write a Python program to find out what the epoch is on a given platform. Also convert a given time in seconds since the epoch.
Python Code :
import time print("\nEpoch on a given platform:") print(time.gmtime(0)) print("\nTime in seconds since the epoch:") print(time.gmtime(36000))
Epoch on a given platform: time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=0, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0) Time in seconds since the epoch: time.struct_time(tm_year=1970, tm_mon=1, tm_mday=1, tm_hour=10, tm_min=0, tm_sec=0, tm_wday=3, tm_yday=1, tm_isdst=0)

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())
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)
