If the condition never becomes False, you get an infinite loop: python while True: print("Forever!") This prints "Forever!" endlessly. Press Ctrl+C to stop it.
Infinite loops are usually bugs. But sometimes they're intentional. A game loop runs until the user quits. A server waits for connections indefinitely.
You control exit with break (covered soon). When debugging, if your program hangs, suspect an infinite loop. Check that your loop variable changes and eventually fails the condition.
