Which of the following for loops would print the following numbers?

0

1

2

3

4

5

• for i in range(5): print(i)

• for i in range(1, 5, 1): print(i)

• for i in range(6): print(i)

• for i in range(0, 5, 1): print(i)

Which of the following for loops would print the following numbers?

3

5

7

9

• for i in range(3, 10, 2): print(i)  

• for i in range(3, 9, 2): print(i)

• for i in range(9): print(i)

• for i in range(3,9): print(i)

What is the value of num when this loop completes?

num = 0

for i in range(2, 8, 2):

num = num + i

• 2

• 8

• 12

• 20

Which of the following for loops will give the same values for i as the loop below?

for i in range(10):

• for i in range(11, 0):

• for i in range(10, 0, -1):

• for i in range(0, 10):

• for i in range(0, 11, 1):

Three of the for loops below will provide identical values for i. Which for loop will provide values that do not match the others?

• for i in range(0, 5):

• for i in range(5):

• for i in range(0, 5, 1):

• for i in range(5, 0, 1):

What does this program print?

temperature = 65

while temperature < 80:

print("It's still a nice day")

if temperature < 70: temperature = temperature + 5

elif temperature > 75:

break

else:

temperature = temperature + 3

• It’s still a nice day It’s still a nice day

• It’s still a nice dayIt’s still a nice dayIt’s still a nice day

• It’s still a nice dayIt’s still a nice dayIt’s still a nice dayIt’s still a nice dayIt’s still a nice day

• It’s still a nice dayIt’s still a nice dayIt’s still a nice dayIt’s still a nice day

Which of the following while loops would continue to loop as long as num has values between the range of 3-12, exclusive?

• while num > 12 and num < 3: # do something with num

• while num < 12 or num < 3: # do something with num

• while num <= 12 and num >= 3: # do something with num

• while num < 12 and num > 3: # do something with num

Which of the following while loops will cause an infinite loop?

• secret_num = 10 while secret_num == 10: secret_num = secret_num - 1

• secret_num = 10 while secret_num == 10: print(secret_num)

• secret_num = 10 while secret_num > 0: secret_num = secret_num - 1

• secret_num = 10 while secret_num != 10: print(secret_num)

When would a while loop be a better control structure to use than a for loop?

• When you need to repeat multiple commands

• When you need to repeat something 5 times

• When you don’t know how many times something will need to repeat

• When the user is inputting how many times to repeat something

What will be printed to the screen when this program is run?

for j in range(2): for i in range(0, 2, 1): print(i)

• 0 1 0 1

• 0 2

• 0 1 0 1 0 1

• 1 2 1 2 1 2
