Python Basics — Variables & Data Types
Chapter 3 — Variables & Data Types
Variables and data types are the building blocks of every Python program. In this chapter, you’ll learn how Python stores and manages data — from simple numbers to text strings and boolean values.
What You’ll Learn
| # | Topic | Description |
|---|---|---|
| 1 | Variables | Creating variables, assignment, dynamic typing, type() |
| 2 | Numbers | Integers, floats, complex numbers, math module |
| 3 | Strings Basics | Creating strings, indexing, escape characters, basic methods |
| 4 | Booleans & None | True/False, truthy/falsy, None type |
| 5 | Type Conversion | Implicit/explicit conversion, casting functions |
| 6 | Practice Exercises | 5 hands-on exercises with solutions |
Why This Matters
Every program works with data. Whether you’re calculating a total, storing a user’s name, or checking whether a condition is true — you need variables and data types.
Python makes working with data easy because it uses dynamic typing — you don’t have to declare variable types in advance. Python figures it out for you.
