As a function, it does take two arguments, and can be called explicitly that way, no? Adjustment is not enough, the message needs to be substantially rewritten. Something like TypeError: invoked as a method, echo() takes exactly 1 argument (0 given) captures the semantics, but is perhaps too verbose. _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
