1. Identifier Rules

• Can contain: letters (a-z, A-Z), digits (0-9), and underscores (_).

1. () — Parentheses
2. ** — Exponentiation
3. +x, -x — Unary plus/minus

5. +, - — Addition, Subtraction
6. ==, !=, <, <=, >, >= — Comparison
7. not, and, or — Logical Operators

3. Falsy Values in Python

• Constants: None, False
• Zero numbers: 0, 0.0, 0j
• Empty sequences/collections: "", [], (), {}, set()
