Actually, I know about generator expressions, but at some point I must have misinterpreted some bug in my code to mean that join in particular didn't like generator expression arguments, and wanted lists. Actually it seems to like anything at all that can be iterated produce a sequence of strings. So I'm glad to find that join is fine after all, and to get that misap[com?:-)]prehension out of my mind ;-) Regards, Bengt Richter -- http://mail.python.org/mailman/listinfo/python-list
