Variables and Data Types

Variables are containers for storing data values. Python is dynamically typed, meaning you don't need to declare variable types explicitly.

Basic Data Types

Integers: Whole numbers without decimals.

Floats: Numbers with decimal points.

Strings: Text enclosed in quotes.

Booleans: True or False values.

Variable Naming Rules

Variable names must start with a letter or underscore, can contain letters, numbers, and underscores, and are case-sensitive.

Type Conversion

Python allows you to convert between types using functions like int(), float(), str(), and bool().
