Should this be labeled (2003)? What's changed since then, any of this that should be revised for whatever's considered the current "stable" Python?

It should have been. Still it's the best learning source I've seen, especially when combined with docs.python.org, particularly the tutorial, what's new, and brief tour of the standard library

Looks like a good high level intro to the language, but it's a bit dated (2003).

I think I saw an old style Python class in there.
