I've also wished for a design patterns book aimed at Python, or at least
dynamic languages with first class functions and modules.  There's a paper
Python book with "Patterns" in the title, but it has precious little content
in it related to design patterns, at least not the GOF variety.

This web book has the word "Patterns" in it, too:

But looks like it's mainly data structures.  

If you do a google search, and also search the Python Cookbook

http://aspn.activestate.com/ASPN/Python/Cookbook/

you can find examples of:

Singleton
Borg
Null
Factory
Observer (including a Publish/Subscribe recipe)
Memento
State
Decorator
Masquerading and Adaptation patterns (Alex Martelli paper)
Template (another Alex Martelli paper)
Chain of Responsibility
Proxy
Prototype

There must be good examples in actual source code out there, too.

I just bought this book as well.  I must have adult ADD, because I do enjoy
the Head First format, though I disdained it at first.

Yup, this is the place.
