Python: Find intersection of two given arrays using Lambda

Python Lambda: Exercise-11 with Solution

Write a Python program to find intersection of two given arrays using Lambda.

Sample Solution:

Python Code :

array_nums1 = [1, 2, 3, 5, 7, 8, 9, 10]
array_nums2 = [1, 2, 4, 8, 9]
print("Original arrays:")
result = list(filter(lambda x: x in array_nums1, array_nums2)) 
print ("\nIntersection of the said arrays: ",result)

Sample Output:

Original arrays:
[1, 2, 3, 5, 7, 8, 9, 10]
[1, 2, 4, 8, 9]

Intersection of the said arrays:  [1, 2, 8, 9]

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

def fibo(a):
    if a <= 1:
        return a
        return fibo(a-1) + fibo(a-2)

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

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