⚙️ Variable Naming Rules

Rule	Example	Valid?
Start with a letter or underscore	_score = 100	✅
Cannot start with a number	1score = 100	❌
No spaces allowed	user name = "Max"	❌
Case-sensitive	Age ≠ age	✅
Use descriptive names	student_age = 15	✅

Best Practices ✨

• Use lowercase letters and underscores (snake_case)
• Pick meaningful names (like score instead of x)
• Avoid Python keywords (e.g., for, class)
