Chapter 9. Tuples, Files, and Everything Else
This chapter rounds out our in-depth look at the core object types in Python by exploring the tuple, a collection of other objects that cannot be changed, and the file, an interface to external files on your computer. As you’ll see, the tuple is a relatively simple object that largely performs operations you’ve already learned about for strings and lists. The file object is a commonly used and full-featured tool for processing files; the basic overview of files here is supplemented by larger examples in later chapters.
This chapter also concludes this part of the book by looking at properties common to all the core object types we’ve met—the notions of equality, comparisons, object copies, and so on. We’ll also briefly explore other object types in the Python toolbox; as you’ll see, although we’ve covered all the primary built-in types, the object story in Python is broader than I’ve implied thus far. Finally, we’ll close this part of the book by taking a look at a set of common object type pitfalls and exploring some exercises that will allow you to experiment with the ideas you’ve learned.
