I'm glad I wasn't the only one who spotted that. There's something very curious about somebody worried about efficiency choosing a *less* efficient solution than what they started with. To quote W.A. Wulf: "More computing sins are committed in the name of efficiency (without necessarily achieving it) than for any other single reason — including blind stupidity." As Donald Knuth observed: "We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil." The Original Poster (OP) is concerned about saving, what, a tenth of a microsecond in total? Hardly seems worth the effort, especially if you're going to end up with something even slower. -- Steve -- https://mail.python.org/mailman/listinfo/python-list
