Loop Tracing Practice¶

Determine what will be printed by each of the code snippets below.

for n in range(3, 10, 2):
    if n % 5 == 0:
        print("bingo", end=" ")
    else:
        print(n, end=" ")

for c in "CS 149!":
    if c.isupper():
        print(c, end="")
    else:
        print("*", end="")

cars = ["Ford", "GM", "Chevy", "Ferrari"]
for i in range(len(cars) - 2):
    i += 1
    print(cars[i])

cars = ["Ford", "GM", "Chevy", "Ferrari"]
for i, c in enumerate(cars):
    if c[0] == "F":
        print(i, c, end=" ")

tallies = {3:1, 8:2, 5:4}
total1 = 0
total2 = 0
for key in tallies:
    total1 += key
    total2 += tallies[key]
print(total1, total2)
