Python Web Development Techdegree Student 15,616 PointsIn the video, the instructor is doing something very specific in order to teach an example of how pop() works. It is not the only way to solve the problem. In this context, he is trying to emphasize that pop() literally removes a value from the list which then would impact the index of the list itself and the contents of the list itself. He presented the option of copying a list to manipulate since it will leave the original list object unchanged.
