While Loops

Learn how to repeat code blocks using while loops and when to use them.

While loops repeat code as long as a condition is True.

Basic While Loop

count = 0
while count < 5:
    print("Count:", count)
    count += 1

User Input Loop

while True:
    answer = input("Type quit to exit: ")
    if answer.lower() == "quit":
        break
    print("You typed:", answer)
