Actually I think assigning the fall-back value in an "else" branch is more readable. To some extent it's just a feeling, but there's two things: For one, it gives you all assignments to the result at closer, if not the same, indentation levels. More importantly, the value is unconditionally set by a single statement, namely the "for" construct, instead of by either the first or both, the second assignment basically making the first superfluous. Using "else" models better what you want to do, IMO. -- Viele Grüße, Thomas _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
