Python: Compare two given lists and find the indices of the values present in both lists
Python List: Exercise - 198 with Solution
Write a Python program to compare two given lists and find the indices of the values present in both lists.
Sample Solution:
Python Code:
def matched_index(l1, l2):
l2 = set(l2)
return [i for i, el in enumerate(l1) if el in l2]
nums1 = [1, 2, 3, 4, 5 ,6]
nums2 = [7, 8, 5, 2, 10, 12]
print("Original lists:")
print(nums1)
print(nums2)
print("Compare said two lists and get the indices of the values present in both lists:")
print(matched_index(nums1, nums2))
nums1 = [1, 2, 3, 4, 5 ,6]
nums2 = [7, 8, 5, 7, 10, 12]
print("\nOriginal lists:")
print(nums1)
print(nums2)
print("Compare said two lists and get the indices of the values present in both lists:")
print(matched_index(nums1, nums2))
nums1 = [1, 2, 3, 4, 15 ,6]
nums2 = [7, 8, 5, 7, 10, 12]
print("\nOriginal lists:")
print(nums1)
print(nums2)
print("Compare said two lists and get the indices of the values present in both lists:")
print(matched_index(nums1, nums2))
Sample Output:
Original lists: [1, 2, 3, 4, 5, 6] [7, 8, 5, 2, 10, 12] Compare said two lists and get the indices of the values present in both lists: [1, 4] Original lists: [1, 2, 3, 4, 5, 6] [7, 8, 5, 7, 10, 12] Compare said two lists and get the indices of the values present in both lists: [4] Original lists: [1, 2, 3, 4, 15, 6] [7, 8, 5, 7, 10, 12] Compare said two lists and get the indices of the values present in both lists: []

Returns True if the provided function returns True for every element in the list, False otherwise:
Example:
def tips_every(lst, fn=lambda x: x): return all(map(fn, lst)) print(tips_every([2, 4, 3], lambda x: x > 1)) print(tips_every([1, 2, 3]))
