Python List: Exercise - 202 with Solution
Write a Python program to find the indexes of all None items in a given list.
def relative_order(lst): result = [i for i in range(len(lst)) if lst[i] == None] return result nums = [1, None, 5, 4,None, 0, None, None] print("Original list:") print(nums) print("\nIndexes of all None items of the list:") print(relative_order(nums))
Original list: [1, None, 5, 4, None, 0, None, None] Indexes of all None items of the list: [1, 4, 6, 7]
