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:")
print(array_nums1)
print(array_nums2)
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]
