Ebook: Hacking RSS and Atom

Apart from being a great book on working with RSS, this is a great Python book. The running theme in the book is extracting information and presenting it in RSS form. Since you have to get the information from somewhere the non-RSS code provides a wealth of documented examples that you can put use in your own projects. It's worth getting this book just for the code samples.

So if you are interested in getting started with Python or you are a competent Python hacker you will definitely learn something by reading the code and be able to add more tricks to your Python toolbox.
