1. Variables
   - Names used to store data.
   - Must start with a letter or underscore. Case-sensitive.
   - Use snake_case (e.g., user_age) by convention.

2. Data Types
   - int: Integers (1, -5, 100)
   - float: Decimal numbers (3.14, -0.01)
   - str: Text ("Hello", 'Python')
   - bool: True or False

3. Arithmetic Operators
   + (Add), - (Sub), * (Mul), / (Div)
   // (Floor Div), % (Modulus), ** (Exponent)

4. Comparison & Logical Operators
   - ==, !=, >, <, >=, <=
   - and, or, not
