Swap first and last values in a list in Python using Slicing

In this approach, we first check if the list has at least $2$ elements. If the list has at least $2$ elements, we swap the first and last elements using Python slicing by assigning the value of the last element to the first element and the value of the first element to the last element. We then slice the list from the second element to the second$-$to$-$last element and concatenate it with a list containing the first element and the last element in their new positions.
