Great example of a python module/package following up to date conventions.

[Big Stu]

I'm hoping someone on here can point me to an example of a python
package that is a great example of how to put it all together.  I'm
hoping for example code that demonstrates:

-Strict adherence to PEP 8
-thorough use of Docstrings
-Conventional directory structure/package layout
-Appropriate use of the latest accepted coding guidelines in the
python community (e.g., new classes versus old classes, Python 3000
compatibility, newer language features, etc. etc.)
-Some amount of object oriented design

Bonus:
-Unit tests
-Logging mechanism

I can't imagine a package that's been around longer than a few years
will hit upon all these things well unless the maintainer went back
and did some serious refactoring and re-tooling.

Is this question possible to answer?
