Oh, just thought of a possible snag. Since an empty string comes up as false, this exact notation would fail if the re can match nothing. But you probably know if it's possible for that to happen, so don't use this simple short-hand. :) ChrisA -- https://mail.python.org/mailman/listinfo/python-list
