Repeat It! (for loops)

Make Python repeat things with for loops and range().

🎯 What you will learn

Remember loops from Code Critters? 🐛 In Python, we write them with for. Get ready to print 100 stars with ONE line!

1. 🔁 for and range

for i in range(3): repeats the indented lines 3 times.

for i in range(3):
    print("Hip hip hooray! 🎉")

2. ↔️ Indent!

Lines inside the loop start with 4 spaces. That’s how Python knows they belong to the loop.

for i in range(2):
    print("inside the loop")
print("after the loop")

3. 🔢 Counting

i counts for you: 0, 1, 2… Add 1 to start at 1.

for i in range(5):
    print(i + 1)

Change the code and press ▶ Run to see what happens. You can’t break anything!

for i in range(5):
    print("⭐" * (i + 1))

for i in range(3):
    print(3 - i)
print("Lift off! 🚀")

Tap a card to flip it over!

Use a loop to print “Coding rocks!” exactly 4 times.

for i in range(1):
    print("Coding rocks!")
