“Programming Python: The Short Story” If you are like most people, when you pick up a book as large as this one, you’d like to know a little about what you’re going to be learning before you roll up your sleeves. That’s what this chapter is for—it provides a demonstration of some of the kinds of things you can do with Python, before getting into the details. You won’t learn the full story here, and if you’re looking for complete explanations of the tools and techniques applied in this chapter, you’ll have to read on to later parts of the book. The point here is just to whet your appetite, review a few Python basics, and preview some of the topics to come. To do this, I’ll pick a fairly simple application task—constructing a database of records—and migrate it through multiple steps: interactive coding, command-line tools, console interfaces, GUIs, and simple web-based interfaces. Along the way, we’ll also peek at concepts such as data representation, object persistence, and object-oriented programming (OOP); explore some alternatives that we’ll revisit later in the book; and review some core Python ideas that you should be aware of before reading this book.

Ultimately, we’ll wind up with a database of Python class instances, which can be browsed and changed from a variety of interfaces. I’ll cover additional topics in this book, of course, but the techniques you will see here are representative of some of the domains we’ll explore later. And again, if you don’t completely understand the programs in this chapter, don’t worry because you shouldn’t—not yet anyway. This is just a Python demo.

We’ll fill in the rest of the details soon enough. For now, let’s start off with a bit of fun. Note Readers of the Fourth Edition of might recognize some aspects of the running example used in this chapter—the characters here are similar in spirit to those in the OOP tutorial chapter in that book, and the later class-based examples here are essentially a variation on a theme. Despite some redundancy, I’m revisiting the example here for three reasons: it serves its purpose as a review of language fundamentals; some readers of this book haven’t read Learning Python; and the example receives expanded treatment here, with the addition of GUI and Web interfaces.

That is, this chapter picks up where Learning Python left off, pushing this core language example into the realm of realistic applications—which, in a nutshell, reflects the purpose of this book. The Task Imagine, if you will, that you need to keep track of information about people for some reason. Maybe you want to store an address book on your computer, or perhaps you need to keep track of employees in a small business. For whatever reason, you want to write a program that keeps track of details about these people.
