Python 2.6 Text Processing: Beginners Guide

By: Jeff McNeil

Overview of this book

<p>For programmers, working with text is not about reading their newspaper on a break; it's about taking textual data in one form and doing something to it. Extract, decrypt, parse, restructure – these are just some of the text tasks that can occupy much of a programmer's life. If this is your life, this book will make it better – a practical guide on how to do what you want with textual data in Python.</p> <p><em>Python 2.6 Text Processing Beginner's Guide</em> is the easiest way to learn how to manipulate text with Python. Packed with examples, it will teach you text processing techniques and give you the skills to work with the most popular Python libraries for transforming text from one form to another.</p> <p>The book gets you going with a quick look at some data formats, and installing the supporting libraries and components so that you're ready to get started. You move on to extracting text from a collection of sources and handling it using Python's built-in string functions and regular expressions. You look into processing structured text documents such as XML and HTML, JSON, and CSV. Then you progress to generating documents and creating templates. Finally you look at ways to enhance text output via a collection of third-party packages such as Nucular, PyParsing, NLTK, and Mako.</p>

Summary


In this chapter, we looked at both regular expression syntax and the Python-specific implementation details. You should have a solid grasp of Python regular expressions and understand how to implement them.

In this chapter, we broke apart a regular expression graphically in order to help you understand how the pieces fit together. We built on that knowledge to parse HTML data, BIND zone files, and even internationalized characters in the Cyrillic alphabet.

Finally, we covered some Python specifics. These are non-portable additions on the Python regular expression implementation.

Our next chapter moves into the processing of structured text documents such as XML and HTML. We'll move away from our system-based examples and create a dungeon-crawling game for a bit of variety.
