السؤال 26

After `items = [1]` and `items.append([2, 3])`, what is `items`?

`[1, 2, 3]`
`[1]` because append returns no value
`[1, [2, 3]]`الإجابة الصحيحة
`[[1], [2], [3]]`

الشرح

The argument to `append` becomes one new final element even though that argument is itself a list. Adding its two contents separately would be the behavior of `extend`, not `append`.
