sometotal = (expression) is valid syntax, and +value is valid syntax. Thus what you wrote is perfectly normal syntax, it's the assignment of a pos'd value, badly formatted. pep8.py will warn against it (it'll complain that the whitespace around `+` is wonky). But I see no justification for disallowing this, anymore than for disallowing the rougly equivalent (and just as error-prone) `sometotal = -somevalue`. _______________________________________________ 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
