Nested loops

explained with cricket overs. Watch the reel, then work through it below: run the code, take the quiz, keep the cheat sheet.

📒 Open the cheat sheet

Sana2 overs, balls in each. How do I count every single ball?

TeacherA loop inside a loop! Overs outside, balls inside. Nested loops!

overs.py

for over in range(2):
    for ball in range(1, 4):
        print(ball, end="")
    print()

TeacherFor every over, the inner loop bowls all its balls. 3 per over, here!

SanaWait, why does the inner one restart at 1?

TeacherEach new over starts the inner loop fresh! The empty print() starts a new line.

⏸ Pause & predict: what prints?

plates = 0
for table in range(2):
    for guest in range(3):
        plates += 1
print(plates)

Next: String indexing →← break & continue
