That's an odd little quirk... never noticed that before. I just use regular expressions myself. Wouldn't this be something worth cleaning up? It's a little confusing for failure to evaluate to boolean true even if the relationship isn't direct. -- http://mail.python.org/mailman/listinfo/python-list
