Amaury Forgeot d'Arc added the comment: The slowdown is due to the new function _PyObject_LengthHint: on my Win2K machine, the command python -m timeit "tuple(1 for _ in xrange(3))" answers: 100000 loops, best of 3: 4.14 usec per loop By adding a line "return rv;" on the second line of _PyObject_LengthHint, I get: 100000 loops, best of 3: 2.71 usec per loop
Should we disable this function for some known built-in types? ---------- nosy: +amaury.forgeotdarc __________________________________ Tracker <[EMAIL PROTECTED]> <http://bugs.python.org/issue1045> __________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
