915 PointsWhy do we use append and extend for lists?
This is probably a silly question, but I just wanted to know why we use append and extend, rather than just going back to the list in your code and editing the elements directly?

The primary use of the list-expanding dynamic methods are for creating and maintaining those lists during the program execution.
