This book is designed specifically with programming beginners in mind. Basic programming concepts — such as expressions, variables, loops, decisions, lists, dictionaries, sets, functions, files, classes, objects, SQLite 3 databases, regular expressions and graphical interfaces with Tkinter — are clearly presented one by one with examples and exercises to illustrate.
The book aims to explore computer programming as an everyday tool. It can be read during an introduction to computer programming course or used as a study guide for self-learners. Only basic computer knowledge, such as typing texts, opening and saving files, is needed to start the course. All software used in the book can be downloaded for free and runs on Windows, Linux, and macOS.

Although Python (version +3.13) is a very powerful language full of modern programming features, this book focuses primarily on programming logic and teaching how to program. Some language features were not used in order to favor programming logic exercises and offer the reader broader preparation for other languages.
Powerful language features such as generators, sets, lambda functions and comprehensions are presented, and the reader will find various notes and explanations of Python-specific features in addition to programming logic.
