Which function removes the last item from a list?

The function that removes the last item from a list is the pop() function. When called without any arguments, pop() will remove the last element of the list and return it. This allows for both modification of the list by removing the element and retrieval of that element for further use.

For example, if you have a list like this: my_list = [1, 2, 3], calling my_list.pop() will remove the last item (which is 3) from the list, resulting in my_list now being [1, 2]. The value 3 will be returned by the pop() function.

The other functions listed serve different purposes. The append() function is used to add a new element to the end of a list, not to remove one. The sum() function is used to calculate the total sum of a list of numbers, and the min() function finds the smallest item in a list. None of these other functions are designed for the specific task of removing the last item from a list.
