Module 02: Data Types

📋 Overview

This module explores Python's built-in data types in depth. Understanding data types is fundamental to effective Python programming, as they determine how data is stored, manipulated, and accessed.

🎯 Learning Objectives

• Master Python's numeric types (int, float, complex)
• Work with strings and string methods
• Understand and manipulate lists
• Use tuples for immutable sequences
• Leverage dictionaries for key-value data
• Apply sets for unique collections
