📆 Day 2: Python Basics - Variables & Data Types
Store data like a pro!

---
📦 What are Variables?
Variables = Containers for storing data

python  
name = "Neo"  # Text in quotes  
age = 30      # Whole number  
height = 6.1  # Decimal number  

Example output:
Neo, 30, 6.1

---

📝 Variable Rules
1. 🚫 Never starts with numbers/symbols (except _)
2. 🔠 Case-sensitive: Age ≠ age ≠ AGE
3. ✅ Allowed: letters, numbers, underscores
Good: user_name, price2
Bad: 2nd_user, my-name

---

🔤 Data Type Zoo
| Type | Example | Use Case |
|------------ |-----------------—-|------------------------———--|
| str | "Hello" | Text data |
| int | 25 | Ages, counts |
| float | 3.14 | Measurements, prices |
| bool | True/False | Switches, conditions |

Check types with:

python  
print(type("Python"))  # Output: <class 'str'>  

---

🎯 Pro Tips
1. Swap variables without temp:

python  
a, b = 5, 10  
a, b = b, a  # Magic!  

2. Assign multiple values:

python  
x, y, z = 10, 20, 30

💻 Practice Time
1. Profile Maker

python  
name = "Your Name"  
age = your_age  
height = your_height  
# Print all in one message  

2. Advanced Swap Challenge
Swap values without using a 3rd variable (Hint: Use math!)
Starting values:
a = 5, b = 10

🎯 Today's Goal
- Create variables confidently ✅
- Name them properly 🏷
- Understand 4 core data types 🔤
