Imagine a game on a map. At the beginning, we might want to randomly assign each player a starting point.

Q:
The following function is supposed to check whether the given list of numbers is in ascending order. For example, we want is_ascending([2, 6, 9, 12, 400]) to return True while is_ascending([4, 8, 2, 13]) should return False. def is_ascending(numbers): “””Returns whether the given list of numbers is in ascending order.””” for i in range(len(numbers)): if numbers[i+1] < numbers[i]: return False return TrueHowever, the function doesn’t quite work. Try it on the suggested tests to verify this for yourself. The easiest fix is to make a small change to the highlighted code. What should it be replaced with?
