I ran an experiment on this a while back. I thought it generated a list. But the results turned out to be surprising. Take this with a grain of salt. I'm not completely sure I did what I meant to do. But it looks like however you do it, it works out about the same. http://www.signalsguru.net/articles/pyloops/pyloops.html -- http://mail.python.org/mailman/listinfo/python-list
