We can loop over strings, too!

The following incomplete function is a simple, but inefficient, way to reverse a string. What line of code needs to replace the questions marks for the code to work correctly?

def reverse_string(s):
"""Returns the reversal of the given string."""
= ""
for char in s:
result = char + result
return result
print reverse_string("hello")

Imagine a game on a map. At the beginning, we might want to randomly assign each player a starting point. Which of the following expressions may we use in place of the question marks to correctly implement this functionality?
import random

def random_point():
"""Returns a random point on a 100x100 grid."""
return (random.randrange(100), random.randrange(100))

def starting_points(players):
"""Returns a list of random points, one for each player."""
points = []
for player in players:
point = random_point()
( points + point, points.extend(point), point.append(points), points.append(point), points += point )
return points

Question 6 of 9

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 ❌):
if numbers[i+1] < numbers[i]:
❌
return True
However, 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?

range(len(numbers)
