Python: Create a function that takes one argument multiplied with an unknown given number
Python Lambda: Exercise-2 with Solution
Write a Python program to create a function that takes one argument, and that argument will be multiplied with an unknown given number.
Python Code :
def func_compute(n): return lambda x : x * n result = func_compute(2) print("Double the number of 15 =", result(15)) result = func_compute(3) print("Triple the number of 15 =", result(15)) result = func_compute(4) print("Quadruple the number of 15 =", result(15)) result = func_compute(5) print("Quintuple the number 15 =", result(15))
Double the number of 15 = 30 Triple the number of 15 = 45 Quadruple the number of 15 = 60 Quintuple the number 15 = 75

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)
