1fill in blank

easy

    print("Looping forever")

Drag options to blanks, or click blank then click option'

BFalse

CNone

DTrue

💡 Hint

Common Mistakes

Using False or 0 as the condition, which stops the loop immediately.

Using None, which is not a boolean and causes an error.

The while True statement creates an infinite loop because the condition is always true.

medium

Complete the code to break out of the infinite loop when user types 'exit'.

Python

while True:
    user_input = input("Type something: ")
    if user_input == [1]:
        break

Drag options to blanks, or click blank then click option'

A"quit"

B"exit"

C"stop"

D"end"

💡 Hint

Common Mistakes

Using words other than 'exit' which do not stop the loop.

Forgetting to put quotes around the string.

The loop breaks when the user types exit, so the condition must check for the string "exit".

3fill in blank

hard

Fix the error in the loop condition to make it an infinite loop.

Python

while [1] == True:
    print("Running")

Drag options to blanks, or click blank then click option'

ATrue

B1

CFalse

D0

💡 Hint

Common Mistakes

Using False or 0 which stops the loop.

Using 1 which works but is less clear than True.

The condition must be True to run infinitely. Using True == True is valid but redundant; just while True: is preferred.

4fill in blank

hard

Fill both blanks to create a loop that asks for a number and stops when the number is 0.

Python

while [1]:
    num = int(input("Enter number: "))
    if num [2] 0:
        break

Drag options to blanks, or click blank then click option'

ATrue

BFalse

C==

D!=

💡 Hint

Common Mistakes

Using while False which never runs the loop.

Using != which breaks on wrong condition.

The loop runs infinitely with while True: and breaks when num == 0.

5fill in blank

hard

Fill all three blanks to create a loop that asks for a password and stops when the correct password is entered.

Python

while [1]:
    pwd = input("Enter password: ")
    if pwd [2] [3]:
        break

Drag options to blanks, or click blank then click option'

ATrue

B==

C"secret123"

D!=

Attempts:

3 left

💡 Hint

Common Mistakes

Using != which breaks on wrong password.

Forgetting quotes around the password string.

The loop runs forever with while True: and breaks when the password equals "secret123".
