Loop Controls (break, continue, pass)

Loops let us repeat code — but sometimes we need more control. What if you want to exit a loop early, skip part of it, or leave space for future logic?

Python provides three helpful keywords: break, continue, and pass.

Let’s go through each of them with examples.

Use break when you want to exit the loop entirely, no matter how many items are left.

for number in range(1, 10):
    if number == 5:
        break
    print("Number:", number)

Explanation:

• This loop prints numbers from 1 to 9.
• But when number == 5, it hits break and exits the loop.
• So the output is: 1, 2, 3, 4

Use continue when you want to skip one iteration and move on.

복사
for number in range(1, 6):
    if number == 3:
        continue
    print("Number:", number)

Explanation:

• This skips number == 3, but keeps looping.
• Output is: 1, 2, 4, 5

pass is used when you need a block of code syntactically, but don’t want to write anything yet.

복사
for letter in "data":
    if letter == "t":
        pass
    print("Letter:", letter)

Explanation:

• When letter == "t", the program does nothing — just moves on.
• This is useful as a placeholder for future logic.
