There's a glitch there, though - should be range(1, 10). Reinhold PS: I'm wondering whether my genexp approach or this one is preferable. Readability is equal, I would say, but how about speed? Brought up a few timeits: Python 2.3 ---------- for i in [x/4.0 for x in range(1, 10)]: 36,9 sec for j in range(1, 10): i = j * 0.25: 33,7 sec Python 2.4 ---------- for i in (x/4.0 for x in range(1, 10)): 32,5 sec for j in range(1, 10): i = j * 0.25: 28,4 sec So what does that tell us? (a) don't use genexps where there is a simpler approach (b) Py2.4 rocks! Reinhold -- http://mail.python.org/mailman/listinfo/python-list
