Swap the Bookends

In a photo booth strip, the first and last photos need to trade places.

Task: write swap_ends(photos) that swaps the first and last values of the list, then returns it.

Change the real list in place, then return that same list. Everything in the middle stays where it is.
photos always has at least one value. With just one, swapping it with itself changes nothing.

Examples

photos = ["smile", "wink", "laugh", "pout"]

returns ['pout', 'wink', 'laugh', 'smile']

photos = [1, 2]

returns [2, 1]
