Python: Common index elements from more than one list

Python List: Exercise - 100 with Solution

Write a Python program to extract common index elements from more than one given list.

Sample Solution:

Python Code:

def extract_index_ele(l1, l2, l3):
    result = []
    for m, n, o in zip(l1, l2, l3):
        if (m == n == o):
            result.append(m)
    return result

nums1 = [1, 1, 3, 4, 5, 6, 7]
nums2 = [0, 1, 2, 3, 4, 5, 7]
nums3 = [0, 1, 2, 3, 4, 5, 7]

print("Original lists:")
print(nums1)
print(nums2)
print(nums3)
print("\nCommon index elements of the said lists:") 
print(extract_index_ele(nums1, nums2, nums3))

Sample Output:

Original lists:
[1, 1, 3, 4, 5, 6, 7]
[0, 1, 2, 3, 4, 5, 7]
[0, 1, 2, 3, 4, 5, 7]

Common index elements of the said lists:
[1, 7]
