Question 1

Which TWO of the following statements about while and for loops are TRUE?

while loops continue to loop while the condition is True and end when the condition evaluates to False

for loops continue with iterations until a condition evaluates to True/False

for loops iterate over a sequence without the user needing to maintain an index to that sequence

while loops iterate over a sequence without the user needing to maintain an index to that sequence

Answer 1

while loops continue to loop while the condition is True and end when the condition evaluates to False

for loops iterate over a sequence without the user needing to maintain an index to that sequence

Question 2

What is the number of iterations the following while loop will perform before terminating?

Answer 2

Infinite

Question 3

inventory = []
item = “”
while item != “quit”:
item = input(“Enter an item to add to the inventory: “)
print(“Adding item:”, item)
