The dragon explains

break — leaving early

  1. The dragon: Sometimes you want to stop a loop RIGHT NOW, before its condition would naturally end it. That's break.

  2. The dragon: break exits the loop immediately — right where it is, mid-pass, no matter what the condition says.

    example.pyPython 3
    room = 0while room < 5:    print(room)    if room == 3:        break    room = room + 1
    Output0 1 2 3

  3. The dragon: room never reaches 5 here — the loop stopped itself the moment room hit 3, three steps before the condition would have.

    example.pyPython 3
    room = 0while room < 5:    print(room)    if room == 3:        break    room = room + 1

  4. The dragon: Not every while loop needs a break, though. Plenty just run their natural course and stop on their own condition.

Quick check

Check your understanding

Say your answer out loud before reading the marked one. Every wrong option is a mistake real beginners make.

  1. Question 1 of 1

    room = 0, while room < 5. The loop prints 0, 1, 2, 3 and then stops. Did room ever reach 5?

    question.pyPython 3
    room = 0while room < 5:    print(room)    if room == 3:        break    room = room + 1
    • No — break exited the loop while room was still 3Correct
    • Yes — the loop always runs until its condition becomes False, break or not
    • It's impossible to tell without running the code

    Why: break stops the loop the instant it runs, regardless of the loop's own condition. room was still 3 — well short of 5 — when the loop ended. That's the whole point of break: an early, deliberate exit.

What you'll practice

Three levels in the game: one guided first try with the shape of the answer already there, then two to solve on your own.

  1. 1

    GuidedYour first try

    The dragon searches 5 rooms, numbered 0 to 4, printing each room number — but STOPS the instant it reaches room 3, where the treasure is. Print rooms 0, 1, 2, 3, then stop — never reach 4.
