Python Code: items = list(reversed(range(12))) items[::3] = range(12, 0, -3) tell me the resulting value of the ‘items’ list and explain
Answer from ChatGPT
The resulting value of the 'items' list after executing the given code will be [9, 6, 3, 12, 10, 7, 4, 1, 11, 8, 5, 2].
Explanation:
Here's the step by step explanation of the given code:
* The 'reversed' function is applied to the range between 0 and 12 (exclusive), which returns the reversed order of integers from 11 to 0. So, the 'items' list will be [11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0].
* The slicing operation [::3] selects every 3rd element in the 'items' list starting from the first element. Thus, it selects [11, 8, 5, 2] from the list.
* The right-hand side of the assignment, which is range(12, 0, -3), creates a new list of integers starting from 12 and decrementing by 3 until 0 (exclusive). So, it generates [12, 9, 6, 3] in reverse order.
* Finally, the selected list [11, 8, 5, 2] is replaced with the new list [12, 9, 6, 3] using the assignment statement. Thus, the resulting value of the 'items' list is [9, 6, 3, 12, 10, 7, 4, 1, 11, 8, 5, 2].
