Indeed, but generally speaking you hardly ever need to manually operate with a __dunder__ method or attribute. They're not quite private, but they are reserved, and normally you would use the public interface. Instead of obj.__dict__[name], one should use one of the attribute functions: getattr(obj, name) setattr(obj, name, 999) delattr(obj, name) Instead of obj.__dict__, one should use vars(obj). And of course, we never write obj.__len__() when we can write len(obj) instead. And so forth. -- Steve _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
