Open Stack

I think you should take a look a this talk:
http://blip.tv/pycon-us-videos-2009-2010-2011/the-lack-of-design-patterns-in-python-2091776
TL;DR: Things that require design patterns in a language like java are so simple in python that they aren't really discussed explicitly.

Subject: [Openstack] 回复： Python Design Patterns in OpenStack

Thanks Dustin,

Actually, my friends learn design patterns from the source code like Java design patterns in Android.

They also learn it from some technical blogs! But after searching "openstack design patterns" in google, there is no useful information.

I am wondering whether the openstack developers will take some notes relevant to design patterns.
I think it can help the beginners to read openstack source code.

Design patterns tend to be fairly abstract concepts, and become part of the general design of a project, rather than being documented explicitly.  So it may be more instructive for you to look for them yourself.

As an example, the way that managers are specified in the configuration files to change the behavior of services is an example of a pattern - which one?

You may also want to look at some smaller Python projects - perhaps discovered by shopping around the cheese shop - to see where they have or have not used patterns, and maybe even practice applying a pattern or two where you think it would improve the project.
