Unconventionally I give you a reference to

http://www.oreilly.com/catalog/pythoncook/chapter/

There you find a link to the sample Chapter 1 of  the Python Cookbook.(PDF)
If all of the book is as well done as this first Chapter it is a 
must-buy I think!

Section 1.5 is: Associating Multiple Values with Each Key in a Dictionary

I certainly couldn't give you an explanation, which surpasses this one
