Solution

The output of the given Python code is [120, 90].

Here's the step by step explanation:

  1. list1[::-2] is a slicing operation in Python. The slicing operation is performed on list1.

  2. The :: operator is a slice operator that can take three arguments - start, stop, and step. If the start and stop arguments are not provided (like in this case), the operation is performed on the entire list.

  3. The -2 as the step argument means that the slicing will start from the end of the list and select every second element.

  4. Therefore, the slicing operation starts from the end of the list (120) and then selects every second element from the end, which is 90.

  5. Hence, the output of the code is [120, 90].
