In my testing that is 3.5x slower than the original solution (and less clear imo). I fixed my version to take a bool default. Either way, I'm not really looking for additional ways to do this in Python unless I've totally missed something. What I am considering is writing it in C, much like filter. -Brad -- http://mail.python.org/mailman/listinfo/python-list
