Just for display purposes, why even need to copy the wishlist when you can just reference any item using index?
Do they not produce the same result anyway?
In 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.
