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 domains -- three of Python's most common applications. 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 are 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.
