Hi! Welcome to the book. You’re going on a tour of all things Python. If you join me and code along with the projects, you’ll have your basic Python programming wings by the end of the book.

Everything in this book you need to know by doing — typing in the code or, better yet, thinking up the code before reading what I’ve done.

About This Book

This book walks you through all the parts you have to know about Python programming. You get examples. I talk about planning programs. And I help link you with the broader Python community so that you can head out there after mastering the projects in this book.

  • Sometimes it’s a separate block of text, like this:

    print('Hello World!')

  • Some code blocks have a >>> at the front of some lines. I’m showing you what happens when you’re using an interactive Python prompt. You need to type the code that follows the >>> in this book into the Python console that’s running on your computer to see what happens:

    >>> my_message = "Hello World!"

    >>> print(my_message)

  • The number of spaces at ...
