Change the Box! 🔄
Here is something cool: you can change what is inside a box anytime!
Take the old thing out, put a new thing in. Like swapping toys! 🧸
box = "apple"
box = "banana"
print(box)Out With the Old 📤
When you put something new in a box, the old thing leaves!
The box only keeps the newest thing. Bye-bye old value! 👋
snack = "chips"
snack = "cookies"
print(snack)New Value Wins 🏅
The last thing you put in the box is what stays.
So the newest value always wins! 🥇
pet = "cat"
pet = "dog"
print(pet)Changing Numbers Too 🔢
You can change number boxes as well!
Start with 5, change it to 10. The box updates! 📈
score = 5
score = 10
print(score)Growing Up! 🎂
Imagine a box for your age. On your birthday, you change it!
From 8 to 9. Happy birthday! 🎉
age = 8
age = 9
print(age)Change It Many Times 🔁
You can change a box as many times as you want!
Each change replaces the old value. So flexible! 🤸

mood = "happy"
print(mood)Print Before and After 👀
You can print the box, change it, then print again to see the difference!
Watch it transform! 🪄
color = "red"
print(color)
color = "blue"
print(color)Old Value Is Gone 🫧
Once you change a box, the old value disappears like a bubble!
The computer only remembers the new one. Pop! 🫧
level = 1
level = 2
print(level)Like Erasing a Whiteboard 🧽
Changing a box is like erasing a whiteboard and writing something new.
The old writing is gone, the new writing stays! ✏️
word = "hi"
word = "bye"

Make a box, then change it to something new, then print it!
See the magic of change. ✨
