Well written open source Python apps

[Ben]

Could anyone suggest an open source project that has particularly well
written Python?  I am especially looking for code that people would
describe as "very Python-ic".  (Not trying to start any kind of war -
just wanted some good examples of a well written Python app to read.)

Thanks!

P.S. - Sorry if this has been discussed at length before - I searched
the group before I posted, but didn't come up with what I was looking
for.
