The OO religion likes to provide a big ego to objects. And be aware! All these egos then want to itch the programmer with question marks for years! And there are programming languages which draw more attention to what some unsolicited objects want, than to what the programmer wants. Python is not so.

Remember, you are the boss. You say: "I want to save all addresses to disk". I'd say: Just dump them to disk unless you feel a functional need in order to make it more indirect.
