Category : Juvenile Nonfiction
Languages : en
Pages : 365
Book Description
The second edition of the best-selling Python for Kids—which brings you (and your parents) into the world of programming—has been completely updated to use the latest version of Python, along with tons of new projects! Python is a powerful programming language that’s easy to learn and fun to use! But books about programming in Python can be dull and that’s no fun for anyone. Python for Kids brings kids (and their parents) into the wonderful world of programming. Jason R. Briggs guides you through the basics, experimenting with unique (and hilarious) example programs featuring ravenous monsters, secret agents, thieving ravens, and more. New terms are defined; code is colored and explained; puzzles stretch the brain and strengthen understanding; and full-color illustrations keep you engaged throughout. By the end of the book, you’ll have programmed two games: a clone of the famous Pong, and “Mr. Stick Man Races for the Exit”—a platform game with jumps and animation. This second edition is revised and updated to reflect Python 3 programming practices. There are new puzzles to inspire you and two new appendices to guide you through Python’s built-in modules and troubleshooting your code. As you strike out on your programming adventure, you’ll learn how to: Use fundamental data structures like lists, tuples, and dictionaries Organize and reuse your code with functions and modules Use control structures like loops and conditional statements Draw shapes and patterns with Python’s turtle module Create games, animations, and other graphical wonders with tkinter Why should serious adults have all the fun? Python for Kids is your ticket into the amazing world of computer programming. Covers Python 3.x which runs on Windows, macOS, Linux, even Raspberry Pi

Did you always want to learn computer programming, but you had to give up because you thought it was difficult? Did you ever believe programming could be fun? If the answer is yes to those questions, you have come to the right place. This book will change the way you think about programming. This book is NOT JUST FOR KIDS. Many adults benefit from a beginner's level, especially with programming. Python is an expressive and powerful language that is very easy to learn and is fun to work with. Most books that will teach you about programming with Python are boring and dull; that's why nobody has fun while learning the language. Luckily, this book will introduce you to the world of programming. It covers the basics of programming with Python and uses examples that feature wizards, monsters, ravens, and much more. You will learn new terms and understand the nitty-gritty of coding as well. Many chapters in the book come with some exercises that you can perform to improve your programming skills and deepen your understanding of the language. You will also learn how to draw using Python in the end. Furthermore, the book will help you: - Work with data structures like lists, tuples, and maps - Organize the statements in the code using functions and modules - Draw different patterns and shapes using the Turtle module - Create some games and applications using Python Why should only adults have all the fun?
