Day 2: Python Variables Adventure

1 What are Variables? 📦

💡 Learn: Variables are like boxes that store information. You can put things in them and take them out!

Try this: Type the code below and click Run. Watch what happens!

name = "Alex"
print(name)

name = "Jordan"
print(name)

🤔 What happened? The variable "name" is like a box. First we put "Alex" in it, then we replaced it with "Jordan"!

2 Numbers vs Text 🔢

💡 Discovery Time: What happens when you add text vs numbers? Try both examples!

print("5" + "3")
print(5 + 3)

print("Ha" * 3)
print(5 * 3)

✨ Cool discovery: "5" + "3" = "53" (text joining), but 5 + 3 = 8 (math!). Text can be multiplied too!

3 Reading Input 🎤

💡 Your Turn: This code asks for YOUR name and age. Click Run and type in the pop-up boxes!

name = input("What's your name? ")
age = input("How old are you? ")
print("Hello", name)
print("You are", age, "years old!")

4 Math Time! ➕➖✖️➗

💡 Challenge: Change the numbers and see different results. What's 100 + 50? Try it!

num1 = 10
num2 = 5

sum = num1 + num2
difference = num1 - num2
product = num1 * num2

print("Sum:", sum)
print("Difference:", difference)
print("Product:", product)

5 Build a Calculator! 🧮

🎯 Puzzle Time! Drag the code pieces below into the correct order to make a working calculator!

📝 Drag from here:

result = num1 + num2

num2 = int(input("Second number: "))

print("=== Calculator ===")

num1 = int(input("First number: "))

print("The answer is:", result)

🎯 Drop in correct order:

🎉 Amazing! You got it right! Now let's run your calculator!

6 Final Project: Age Calculator 🎂

🚀 Big Challenge: This program calculates how many days old you are! Run it and try it out!

name = input("What's your name? ")
age = int(input("How old are you? "))

days = age * 365
hours = days * 24

print(name + ", you are approximately:")
print(days, "days old!")
print(hours, "hours old!")

💪 Extra Challenge: Can you add a line to calculate minutes? (Hint: multiply hours by 60!)
