19.1. "Give Me an Order of Persistence, but Hold the Pickles"

So far in this book, we've used Python in the system programming, GUI development, and Internet scripting domainsthree of Python's most common applications, and representative of its use as an application programming language at large. In the next three chapters, we're going to take a quick look at other major Python programming topics: persistent data, data structure techniques, and text- and language-processing tools. None of these is covered exhaustively (each could easily fill a book alone), but we'll sample Python in action in these domains and highlight their core concepts. If any of these chapters spark your interest, additional resources are readily available in the Python world.
