Python: Multiply each number of given list with a given number using lambda function
Python Lambda: Exercise-21 with Solution
Write a Python program that multiply each number of given list with a given number using lambda function. Print the result.
Python Code :
nums = [2, 4, 6, 9 , 11] n = 2 print("Original list: ", nums) print("Given number: ", n) filtered_numbers=list(map(lambda number:number*n,nums)) print("Result:") print(' '.join(map(str,filtered_numbers)))
Original list: [2, 4, 6, 9, 11] Given number: 2 Result: 4 8 12 18 22

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)
