Marc-Andre Lemburg added the comment: The localization using keyword parameters is a very old trick to avoid global lookups. It does give a noticeable speedup, esp. when the localized variables are used in tight loops or the function itself is used in such loops.
The 5% speedup Steven measured matches my experience with this trick as well. In some cases, it can provide a more dramatic speedup, but this depends a lot on how the code is written. ---------- nosy: +lemburg _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue29724> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
