Introduction to Computer Science & Python Programming

Learn Python the Simple, Practical, Hands-On Way

If you've ever wanted to learn programming but didn't know where to start, this book is for you.

Introduction to Computer Science & Python Programming takes complete beginners from "what is a computer?" to writing real Python programs - step by step, with hands-on practice at every stage. No prior experience required. No technical jargon. Just clear explanations, practical examples, and a proven learning path that genuinely works.

Drawing on more than 15 years of combined teaching experience - over a decade teaching coding to school students and 15 years teaching at university level - every chapter has been refined through real classroom feedback. The result is a learning path that works in practice, not just in theory.

• Complete beginners of any age - readers who have never written a line of code.
• Middle and high school students who want to learn programming quickly and practically.
• Primary and secondary school teachers wanting to learn Python themselves and prepare engaging classroom lessons.
• Future university students heading into computer science, IT, or engineering who want a strong head start.
• Curious self-taught learners looking for a clear, no-fluff introduction to coding.

• The foundations of computer science - hardware, software, binary, and algorithms.
• How to set up Google Colab (free!) and run your first Python program in minutes.
• Variables, data types, decisions, and loops - the building blocks of every program.
• Working with strings, lists, tuples, sets, and dictionaries.
• Drawing with Turtle Graphics, building your own functions, and using powerful Python libraries.
• Reading files, handling errors, and an introduction to Object-Oriented Programming.

• Hands-on from page one - write real Python on day one, not week three.
• Project-based - every concept is reinforced with practical exercises and mini-projects.
• Step-by-step - each chapter builds gently on the last, with no surprises.
• Classroom-tested - based on real lessons taught to hundreds of students.
• Modern tools - uses Google Colab so you can code on any device, instantly.
• Foundations of all programming - master these concepts and you can learn any language.

• 16 progressive chapters from absolute basics to Object-Oriented Programming.
• 70+ hands-on coding projects with a clear What / How / Why / Plan / Code structure.
• 80+ Self-Tasks with worked solutions to test your understanding.
• Quick Quizzes at the end of every chapter to lock in the learning.
• Real-world examples drawn from games, social media, school, and everyday technology.

Whether you're a student, a teacher, a future university student, or simply curious about how technology works - this book gives you everything you need to start coding with confidence.
