Introduction

Why Python? (Popularity, versatility, readability)
Setting up Your Environment (Installing Python, text editors/IDEs)
Your First Program (“Hello, World!” and basic output)
Interactive Mode vs. Scripts

Chapter 2: Basic Building Blocks

Data Types
Numbers (integers, floats)
Strings (text)
Booleans (True/False)
Variables (Storing and naming values)
Operators
Arithmetic (+, -, *, /, %, //)
Comparison (==, !=, <, >, <=, >=)
Logical (and, or, not)
Input from the User (input() function)
Example: Body Mass Index (BMI) Calculator

Chapter 3: Control Flow

Conditional Statements
if, elif, else
Nested conditionals
Loops
for loops (iterating over sequences)
while loops (repeating with a condition)
break and continue
Example: Number Guessing Game

Chapter 4: Functions

Defining Functions (def keyword)
Parameters and Arguments
Return Values
Docstrings (Commenting for clarity)
Scope (Global vs. local variables)
Example: Fibonacci Sequence Generator

Chapter 5: Data Structures

Lists (Ordered collections)
Accessing, indexing, slicing
Modifying lists (append, remove, etc.)
Tuples (Immutable collections)
Dictionaries (Key-value pairs)
Sets (Unordered, unique elements)
Example: Student Grade Management System

Chapter 6: Working with Files

Opening and Closing Files
Reading from Files
Writing to Files
with statement (Context manager)
Example: Simple Text Analyzer

Chapter 7: Modules and Packages

Importing Modules (import)
Standard Library (math, os, datetime, etc.)
External Packages (Installing with pip)
Creating Your Own Modules
Example: Using the requests Module for Web Interaction

Chapter 8: Object-Oriented Programming (OOP)

Classes and Objects
Attributes and methods
__init__ constructor
Inheritance (Creating hierarchies)
Polymorphism (Method overriding)
Encapsulation (Data hiding)
Example: Building a Shape Calculator (Area and Perimeter)

Chapter 9: Error Handling

try and except blocks
Common Exception Types (ValueError, TypeError, etc.)
Raising Your Own Exceptions

Chapter 10: Advanced Topics (Select a Few)

Decorators
Generators
Regular Expressions
Data Science Libraries (NumPy, Pandas)
Web Development Frameworks (Django, Flask)
