If your list is two elements you could use [-2] to get the first element because negative index start with[-1] not [0].

but if your list is just one element you still can use[-1] not [-2] because it will be out of range.

Good luck :)

Using [-2] would be out of range if your list only has one element. If you had two elements, [-2] would actually list your first element!. It's an easy way to list elements at the end of the list without having to count how many elements there are.
