Counting Loops 🔢

Hi, number ninja! 🥷 Today we learn the for loop with range(). It is the best way to count and repeat! 🎉

The for Loop Shape 📐

A for loop looks like this: for i in range(5): then indented code below. It runs 5 times!

for i in range(5):
    print("Hi! 👋")

What Is range()? 🎯

range(5) gives the numbers 0, 1, 2, 3, 4. It starts at 0 and stops BEFORE 5! 🤓

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

Starts at Zero! 0️⃣

Computers love counting from 0! So range(3) gives 0, 1, 2. That is three numbers!

for i in range(3):
    print(i)

The Counter i 🔢

The i is our counter. Each loop, it holds the next number. You can use any name, but i is popular!

for i in range(4):
    print("Step " + str(i))

What Is str()? 🔤

To join a number with a string, we wrap it in str() to turn it into text first! 🪄

for i in range(3):
    print("Number is " + str(i))

Count to 10 🔟

Let us count from 0 to 9 (that is 10 numbers because we start at 0)!

for i in range(10):
    print(i)

Repeat a Message 📢

We do not always need i. We can just repeat a message!

for i in range(3):
    print("You are awesome! 🌟")

Counting Treasures 💎

Let us count treasures we collected on our adventure!

for i in range(5):
    print("Found treasure #" + str(i))

Birthday Candles 🎂

Light up some candles with a loop! One for each number.

for i in range(6):
    print("Candle 🕯️")

You Can Count! 🎉

Wonderful! Try counting from 0 to 4 and printing each number.

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

Quick Check 🧠

Quiz time! 🎯 What numbers does range(3) give?

Recap Time! 🌟

Super counting! 🎓 Today you learned:

  • for i in range(n) repeats n times
  • range starts at 0
  • i is the counter
  • str() turns a number into text

You are a counting champion! 🏆
