The getattr way. If you just need a default value, getattr is a shorter version of try/except. x = getattr(self, 'x', default_value) If the default value is expensive to construct, then you'll end up with something like this: x = getattr(self, 'attr', None) if x is None: x = CreateDefaultValue() self.attr = x.
