But isn't that syntactically equivalent of this? sites_string = args.sites or self.config['sites'] Seems to be what you're looking for with "or else" unless I misunderstand what you're proposing. Doing a bit of testing in the interpreter and I find that a combination of Python's truthiness semantics and short-circuit evaluation seems to give a consistent result. Consider: 'a word' or False => 'a word' 'a word' or True => 'a word' False or 'a word' => 'a word' True or 'a word' => True Is this similar to what you'd expect with "or else?" -- https://mail.python.org/mailman/listinfo/python-list
