An accessible yet rigorous crash course on recursive programming using Python and JavaScript examples.Recursion has an intimidating reputation: it's considered to be an advanced computer science topic frequently brought up in coding interviews. But there's nothing magical about recursion. The Recursive Book of Recursion uses Python and JavaScript examples to teach the basics of recursion, exposing the ways that it's often poorly taught and clarifying the fundamental principles of all recursive algorithms. You'll learn when to use recursive functions (and, most importantly, when not to use them), how to implement the classic recursive algorithms often brought up in job interviews, and how recursive techniques can help solve countless problems involving tree traversal, combinatorics, and other tricky topics. This project-based guide contains complete, runnable programs to help you learn: How recursive functions make use of the call stack, a critical data structure almost never discussed in lessons on recursionHow the head-tail and "leap of faith" techniques can simplify writing recursive functionsHow to use recursion to write custom search scripts for your filesystem, draw fractal art, create mazes, and moreHow optimization and memoization make recursive algorithms more efficient Al Sweigart has built a career explaining programming concepts in a fun, approachable manner. If you've shied away from learning recursion but want to add this technique to your programming toolkit, or if you're racing to prepare for your next job interview, this book is for you.

Learn to program with Python by making and hacking ciphers - no experience required!

A book of 144 sudoku puzzles, ranging from easy to very hard. Any nine symbols can be used for a sudoku puzzle, so the puzzles in this book use emoji characters instead of numbers. Each puzzle blends the deductive logic of sudoku puzzles with the imagery of emoji characters.

The bestselling introduction to Python programming, revised to include the latest Python features, improved explanations, and new chapters about databases and sound files.If you’ve ever spent hours renaming files or updating hundreds of spreadsheet cells, you know how tedious tasks like these can be. But what if you could have your computer do them for you?In this fully revised edition of the best-selling classic Automate the Boring Stuff with Python, you’ll learn how to use Python to write programs that do in minutes what would take you hours to do by hand—no prior programming experience required. You'll learn the basics of coding in Python and explore the language’s’s rich library of modules for performing specific tasks, like scraping data from websites, searching for text across multiple files, and merging, watermarking, or encrypting PDFs.The third edition includes:Expanded coverage of developer techniques, like creating command line programsUpdated examples and new projectsAdditional chapters about working with SQLite databases, speech-recognition technology, video and audio editing, and text-to-speech capabilitiesSimplified explanations (based on reader feedback) of beginner programming concepts, like loops and conditionalsEven if you've never written a line of code, Automate the Boring Stuff with Python, 3rd Edition will teach you how to make your computer take on tedious tasks and do all your grunt work—the way it should be!

Making Games with Python & Pygame is a programming book that covers the Pygame game library for the Python programming language. Each chapter gives you the complete source code for a new game and teaches the programming concepts from these examples. The book is available under a Creative Commons license and can be downloaded in full for free from http: //inventwithpython.com/pygame This book was written to be understandable by kids as young as 10 to 12 years old, although it is great for anyone of any age who has some familiarity with Python.
