I can only speak for myself, but the whole idea of design patterns is
broken. The existence of nontrivial design patterns indicates language
deficiencies. For more extensive corroborating discussions, see:
http://www.codinghorror.com/blog/2005/06/are-design-patterns-how-languages-evolve.html
http://c2.com/cgi/wiki?AreDesignPatternsMissingLanguageFeatures

Python thankfully has relatively few/minor deficiencies (so long as
one judges it within its dynamic language niche), so design patterns
per se aren't too relevant to it.

The canonical Python-specific design pattern is Borg
(http://code.activestate.com/recipes/66531-singleton-we-dont-need-no-stinkin-singleton-the-bo/
) [a variation on Singleton], and nowadays it (like its parent,
Singleton) is considered to be of dubious utility/advisability.

The closest alternative would be some publication that gave examples
of using some of Python's fancier, higher-level features, such as
metaclasses and context managers. I haven't been in the market for
such a book, so I have no good recommendations to give. Closest I
could suggest would be the Language Reference
(http://docs.python.org/reference/ ) and relevant PEPs
(http://www.python.org/dev/peps/ ; they tend to include examples by
way of motivating use-cases).

I am glad you agree.

Cheers,
Chris
