BRIDGE THE GAP BETWEEN NOVICE AND PROFESSIONALYouve completed a basic Python programming tutorial or finished Al Sweigarts bestseller, Automate the Boring Stuff with Python. Whats the next step toward becoming a capable, confident software developer?Welcome to Beyond the Basic Stuff with Python. More than a mere collection of advanced syntax and masterful tips for writing clean code, youll learn how to advance your Python programming skills by using the command line and other professional tools like code formatters, type checkers, linters, and version control. Sweigart takes you through best practices for setting up your development environment, naming variables, and improving readability, then tackles documentation, organization and performance measurement, as well as object-oriented design and the Big-O algorithm analysis commonly used in coding interviews. The skills you learn will boost your ability to program--not just in Python but in any language.Youll learn: Coding style, and how to use Pythons Black auto-formatting tool for cleaner code Common sources of bugs, and how to detect them with static analyzers How to structure the files in your code projects with the Cookiecutter template tool Functional programming techniques like lambda and higher-order functions How to profile the speed of your code with Pythons built-in timeit and cProfile modules The computer science behind Big-O algorithm analysis How to make your comments and docstrings informative, and how often to write them How to create classes in object-oriented programming, and why theyre used to organize code Toward the end of the book youll read a detailed source-code breakdown of two classic command-line games, the Tower of Hanoi (a logic puzzle) and Four-in-a-Row (a two-player tile-dropping game), and a breakdown of how their code follows the books best practices. Youll test your skills by implementing the program yourself.Of course, no single book can make you a professional software developer. But Beyond the Basic Stuff with Python will get you further down that path and make you a better programmer, as you learn to write readable code thats easy to debug and perfectly PythonicRequirements: Covers Python 3.6 and higher

Learn how to program in Python while making and breaking ciphersalgorithms used to create and send secret messages! After a crash course in Python programming basics, youll learn to make, test, and hack programs that encrypt text with classical ciphers like the transposition cipher and Vigenere cipher. Youll begin with simple programs for the reverse and Caesar ciphers and then work your way up to public key cryptography, the type of encryption used to secure todays online transactions, including digital signatures, email, and Bitcoin.Each program includes the full code and a line-by-line explanation of how things work. By the end of the book, youll have learned how to code in Python and youll have the clever programs to prove it!Youll also learn how to:- Combine loops, variables, and flow control statements into real working programs- Use dictionary files to instantly detect whether decrypted messages are valid English or gibberish- Create test programs to make sure that your code encrypts and decrypts correctly- Code (and hack!) a working example of the affine cipher, which uses modular arithmetic to encrypt a message- Break ciphers with techniques such as brute-force and frequency analysisTheres no better way to learn to code than to play with real programs. Cracking Codes with Python makes the learning fun!

An accessible yet rigorous crash course on recursive programming using Python and JavaScript examples.Recursion has an intimidating reputation: its considered to be an advanced computer science topic frequently brought up in coding interviews. But theres nothing magical about recursion. The Recursive Book of Recursion uses Python and JavaScript examples to teach the basics of recursion, exposing the ways that its often poorly taught and clarifying the fundamental principles of all recursive algorithms. Youll 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 recursion How the head-tail and leap of faith techniques can simplify writing recursive functions How to use recursion to write custom search scripts for your filesystem, draw fractal art, create mazes, and more How optimization and memoization make recursive algorithms more efficient Al Sweigart has built a career explaining programming concepts in a fun, approachable manner. If youve shied away from learning recursion but want to add this technique to your programming toolkit, or if youre racing to prepare for your next job interview, this book is for you.

Invent Your Own Computer Games with Python will teach you how to make computer games using the popular Python programming languageeven if youve never programmed before!Begin by building classic games like Hangman, Guess the Number, and Tic-Tac-Toe, and then work your way up to more advanced games, like a text-based treasure hunting game and an animated collision-dodging game with sound effects. Along the way, youll learn key programming and math concepts that will help you take your game programming to the next level.Learn how to:Combine loops, variables, and flow control statements into real working programsChoose the right data structures for the job, such as lists, dictionaries, and tuplesAdd graphics and animation to your games with the pygame moduleHandle keyboard and mouse inputProgram simple artificial intelligence so you can play against the computerUse cryptography to convert text messages into secret codeDebug your programs and find common errorsAs you work through each game, youll build a solid foundation in Python and an understanding of computer science fundamentals.What new game will you create with the power of Python?The projects in this book are compatible with Python 3.
