🐍 Python Mission #2: The Super Calculator! ➕➖✖️➗

📖 Story: Zogg Needs Numbers! 👽

Last time, we helped Zogg, the little alien, by sending a secret message using Python! 🛸 But now, Zogg has a new problem…

“Oh no! My spaceship’s fuel is running out! I need to calculate how much energy I have left. But I don’t know how to do math in Python! Can you help me?“

Zogg needs us to teach Python how to do math so he can safely return home! 🚀 Let’s get started!

🔢 Python as a Super Calculator

Python is great at solving math problems—just like a real calculator! You can add, subtract, multiply, and divide using simple symbols:

Let’s try it out in Python!

📝 Step 1: Open Your Python Playground

Use one of these free online compilers (no sign-up needed!):
🔹 Trinket – Python Online (Recommended ✅)
🔹 OnlineGDB – Python Compiler
🔹 Programiz – Python Online Compiler

🖥️ Step 2: Try Simple Math in Python!

Type this code into your Python playground and hit Run ▶️:

print(5 + 3)
print(10 - 4)
print(7 * 2)
print(16 / 4)

What do you see? 🎉 Python calculates the answers for you!

🧐 What If We Try Bigger Numbers?

Let’s help Zogg by calculating his spaceship’s energy! Try this:

print(1000 - 250)  # Fuel left after using 250
print(50 * 8)      # Energy from solar panels
print(200 / 5)     # Energy used per hour

Python can handle big numbers too! 🚀

🤔 What Happens with Division?

Try this code:

print(10 / 3)

Python gives 3.3333333333333335. That’s because division in Python always gives a decimal number (float)!

If you only want the whole number, use // (integer division):

print(10 // 3)  # Only shows 3

This is useful if Zogg only has whole fuel tanks left! ⛽

🎯 Challenge: Solve Zogg’s Energy Problem!

Zogg’s spaceship needs 3 fuel tanks to reach home. Each fuel tank holds 500 units of energy.

🚀 Mission: Write a Python program to find out how much total energy Zogg has!

Hint: Use multiplication (*) to calculate:

print( ___ * ___ )  # Fill in the blanks!

Post your answer in the comments! 👇

⚠️ Common Mistakes and Fixes!

❌ Forgetting parentheses in print()

print 5 + 3   # ❌ ERROR!

✅ Fix:

print(5 + 3)  # ✅ Works!

❌ Using x instead of * for multiplication

print(5 x 3)  # ❌ ERROR!

✅ Fix:

print(5 * 3)  # ✅ Works!

🌟 Fun Fact: Python Can Handle HUGE Numbers!

Unlike regular calculators, Python can work with really big numbers! Try this:

print(999999999999999 * 2)

Python will still give you the correct answer! 🤯

🚀 What’s Next?

Zogg is one step closer to launching his spaceship! Next time, we’ll learn how to store numbers in variables so Zogg can keep track of his fuel automatically!
