Learn to Program. For Free.

Learning to program makes you a smarter and more capable human being. Rocket science uses programming, but programming isn't rocket science. Whether you're a student preparing for a software career, an office worker with a folder full of spreadsheet files, or a hobbyist who wants to make video games, the Python programming language is an excellent start in the world of programming.

I'm Al Sweigart, and I write books to teach beginners to code. I put them online for free because programming is too valuable and needs to be accessible to all. (You can also buy print and ebooks versions.) My approach takes out the intimidation so that you can become productive and enjoy the creative aspects of coding.

Get started today. And good luck on your programming journey!

Programming Books by Al Sweigart

Cover of Automate the Boring Stuff with Python

Everyone in the 21st century needs to learn to code, right? But not everyone needs to become a software engineer or computer scientist. Automate the Boring Stuff with Python is written for office workers, students, administrators, and anyone who uses a computer how to write small, practical programs to automate tasks on their computer.

You don't need to know all the complexities of algorithms and syntax, you just want to write basic programs to automate mundane computer tasks. In the process, even total beginners will learn to use Python to control their computers without having to learn complex information about computer science. This is a practical programming guide for the rest of us.

Cover of The Big Book of Small Python Projects

If you’re tired of standard step-by-step tutorials, you’ll love the learn-by-doing approach of The Big Book of Small Python Projects. It’s proof that good things come in small programs! Watch a video trailer of the projects in this book.

If you’ve mastered basic Python syntax and you’re ready to start writing programs, you’ll find The Big Book of Small Python Projects both enlightening and fun. This collection of 81 Python projects will have you making digital art, games, animations, counting pro- grams, and more right away. Once you see how the code works, you’ll practice re-creating the programs and experiment by adding your own custom touches.

These simple, text-based programs are 256 lines of code or less. And whether it’s a vintage screensaver, a snail-racing game, a clickbait headline generator, or animated strands of DNA, each project is designed to be self-contained so you can easily share it online.

You’ll create:

  • Hangman, Blackjack, and other games to play against your friends or the computer
  • Simulations of a forest fire, a million dice rolls, and a Japanese abacus
  • Animations like a virtual fish tank, a rotating cube, and a bouncing DVD logo screensaver
  • A first-person 3D maze game
  • Encryption programs that use ciphers like ROT13 and Vigenère to conceal text
