What's happening is that you're paying attention to the values returned by id(), when you should not. The fact that CPython returns a VM address when you call id() is just an "accident" of that particular implimentation. You shouldn't assume that id() returns anything other than a number that is unique to each object. Any time you spend worrying about how that number is calculated is proably wasted. > I expected myName[0] to be located at the same memory location as the myName > variable itself.
