This book is an in-depth and activity-based introduction to Python programming. It follows a step-by-step practical approach by combining the theory of the language with hands-on coding exercises including quizzes, projects, assignments and exams.We begin by setting up the development environment and cover the basics of Python language like comments, operations, data types, variables, functions, conditional statements, loops, strings and comprehensions. Further we cover all the main data structures in Python like Lists, Dictionaries, Tuples and Sets in detail. At the end of each chapter there is a coding quiz of ten questions. We build three projects which are Turtle, Words and Snake Game and after each one there will be an assignment. And finally we have the final exam, which will let you to test your Python level.By the end of the book, you will learn all the fundamental concepts of Python in great detail by writing thousands of lines of code. All the supplementary resources (code files, quizzes, assignments, final exam etc.) are available for download at the Github repository. The link for the repository is provided in the book.Here is what you will find in this Theory: In each topic, we will cover all the Theoretical Details with example coding.True False (42 questions): We will have True False questions at the end of the sub-topics.Coding Exercises (120 questions): At the end of each chapter, we will have Coding Exercises that is a Quiz of 10 questions.Projects (3): We will have 3 Projects in this book. You will learn how to apply Python concepts on real-world problems.Assignments (3): After each project, you will have an Assignment. These assignments will let you build the project from scratch on your own.Final Exam: At the end of this book you will have the Final Exam. It is a multiple choice exam with 20 questions and a limited duration.Contents1. Introduction2. Getting Started3. The First Program4. Variables5. Functions I6. Project 1 - Functions7.
