Python's .append() takes an object as an argument and adds it to the end of an existing list, right after its last element: >>> >>> numbers = [1, 2, 3] >>> numbers. append(4) >>> numbers [1, 2, 3, 4] Every time you call .append() on an existing list, the method adds a new item to the end, or right side, of the list.
