My 2 cents: as an user, I often split very long text lines (mostly log entries or exception messages) into multiple lines in order to stay under 80chars (PEP8 docet), like: log.warning("Configuration item '%s' was renamed to '%s'," " please change occurrences of '%s' to '%s'" " in configuration file '%s'.", oldkey, newkey, oldkey, newkey, filename) This should become (if I understand the proposal) something like: log.warning("Configuration item '%s' was renamed to " % oldkey + "'%s', please change occurrences of '%s'" % (newkey, oldkey) + " to '%s' in configuration file '%s'." % (newkey, filename)) but imagine what would happen if you have to rephrase the text, and reorder the variables and fix the `+` signs... On the other hands, I think I've only got the ``func("a" "b")`` error once or twice in my life. .a. -- antonio.s.messina@gmail.com antonio.messina@uzh.ch +41 (0)44 635 42 22 GC3: Grid Computing Competence Center http://www.gc3.uzh.ch/ University of Zurich Winterthurerstrasse 190 CH-8057 Zurich Switzerland
