Unpacking with star at the front

Question

Accepted Answer

The starred variable can appear at any position - left, middle, or right. Here *rest is on the left, so it captures everything except the final element. 'last' gets 40, and rest is [10, 20, 30]. Like always, the starred result is a list, not a tuple. This pattern is handy for peeling off the last item, just as first, *rest = ... peels off the first.
