At this point, you should be able to write programs using lists. #figure(table( columns: 2, align: left, inset: 6pt, table.header([Function], [Description]), [append(element)], [Adds the specified element to the end of a list.], [remove(element)], [Removes the specified element from the list if the element exists.], [pop()], [Removes the last element of a list.], [max(list)], [Returns the maximum element of the list specified.], [min(list)], [Returns the maximum element of the list specified.], [sum(list)], [Returns the summation of a list composed of numbers.], [sort()], [Sorts a list on which the method is called in ascending order.], [reverse()], [Reverses the order of elements in a list.], [copy()], [Makes a complete copy of a list.], ))
