Python: Find intersection of two given arrays using Lambda

Python Lambda: Exercise-11 with Solution

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

Sample Solution:

Python Code :

# Define two lists 'array_nums1' and 'array_nums2' containing integers
array_nums1 = [1, 2, 3, 5, 7, 8, 9, 10]
array_nums2 = [1, 2, 4, 8, 9]

# Display a message indicating that the following output will show the original arrays
print("Original arrays:")
print(array_nums1)  # Print the contents of 'array_nums1'
print(array_nums2)  # Print the contents of 'array_nums2'

# Use the 'filter()' function with a lambda function to find the intersection of 'array_nums1' and 'array_nums2'
# Filter out elements from 'array_nums2' that are also present in 'array_nums1' using the lambda function
result = list(filter(lambda x: x in array_nums1, array_nums2))

# Display the intersection of the two arrays ('array_nums1' and '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]
