Python is one-statement-per-line, which is already a pretty good limiter of line length. Just don't go crazy with ternary operators (which are hard to read anyway and thus against the Zen for more than the trivial cases) or literal definitions.

My FOSS libraries follow a 120-character wrapping limit and avoids alignment, but otherwise follows PEP-8. The main reason it was upped was the stupid arbitrary wrapping of lines that were only a few characters over the limit.
