I prefer to say that as "if a is true-ish then return a otherwise return b" or even "if a quacks like a true value then return a otherwise return b" to emphasis that this is a form of duck-typing, and avoid any confusion with "if a is True". But otherwise, well said. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
