Stuck? The idea behind lists
A list keeps several values in order: [3, 9, 1]. Its items are numbered from 0, like a string's characters.
append() adds to the end; sum(), min(), max(), len() and sorted() work on a whole list. Read numbers from one line with input().split() and int().
numbers = [int(x) for x in input().split()] print(sum(numbers), max(numbers)) numbers.append(0) print(numbers)
Watch for: split() gives text: "10" sorts before "9". Turn each item into a number before comparing or adding.
