Learn to code and you ve read that python is a good place to start.. but now what? many people who want to program dont know where to start. The idea that you can create"anything"with code is paralyzing This book provides a clear goal: learn Python by creating a text adventure This book will teach you the fundamentals of programming, including how to organize code and some coding best practices. By the end of the book, you will have a working game that you can play or show off to friends. You will also be able to change the game and make it your own by writing a different story line, including adding new items, creating new characters, etc. Learning to program is an exciting endeavor, but can feel daunting at first. However, if you stick with it, you could become a professional programmer or a weekend hobbyist, or both! My story is similar to the stories of many programmers: The first thing I programmed was a number guessing game in QBASIC and now programming is my job. I hope that you, too, can join us, and i thank you for choosing this book as the place to start o Phillip Johnson 2018 P. Johnson, Make Your Own Python Text Adventure htos:// doi. org/10.1007/978-1-4842-3231-6_1 CHAPTER 1 GETTING STARTED Who this book is for This book is intended for people who have never programmed before or for novice programmers starting out with Python. If you're in this second group, you can probably skim some of the early material Although this is geared toward beginners, I do make some assumptions that you know computer basics such as opening a command prompt, installing software, etc. If you get stuck on anything an Internet search for "how to do [ thing] on [operating system]"will typically help you out. Particularly useful web sites for programmers are StackOverflow (http://stackoverflow.comandSuperuser(http://superuser.com),2 so if you see them in your search results, give them a shot first How To Use this book In each chapter of the book, you will make progress on the overall goal of creating your text adventure The early chapters may seem like slow going because they focus on learning the basics of Python. Things will pick up in the second half of the book, when the focus shifts toward building the game world I suggest reading this book on or beside your computer so you can easily go back and forth between reading and writing code. Each of the chapters in the first half of the book will end with a homework section These problems won't be required for the main game, but you should at least try them When applicable, solutions are provided at the end of the book Most of the python code in this book will look like this greeting ="Hello, World print (greeting) Thttp://stackoverflow.com http://superuser.com CHAPTER 1 GETTING STARTED Code that is intended to be entered into an interactive python session (see Chapter 3) will look like this >>> greeting ="Hello, World! >>>print(greeting) References to code or commands that appear inline will appear like this. Technical terms that you should learn appear like this If you ever get stuck, you can download the code for each chapter in the book here. Resist the urge to copy and paste everything! Youll retain more information if you type out the code. However, we all make mistakes, so if you cant figure out what's wrong, you can compare your code against mine. If you re really sure everything is the same, double-check with an online comparison tool like DiffChecker or Mergely You can also check Appendix b for some common errors you may run into Finally, this game is your game. It is fully customizable, and if you feel comfortable adding more rooms and enemies, changing the story, making it more difficult, etc. please do so. I will point out good customization opportunities like this Customization Point Some notes about customization Keep in mind that each chapter builds on the last, so if you deviate too far from the material, you may want to save your customized code in another directory so you can keep learning from the source material shttps://www.dropboxcom/sh/udvdkxtjhtlgdh1/aad9hod6vtb5rgfz7k Bv-ghua?dl=o Ahttps://www.difFchecker.com 5http://www.mergeLy com/editor
