  1. the convention is a leading underscore, _foo, is private, and all that means is that clients should not use it nor rely on it. and then there is name-mangling (double leading underscore), that merges the instance name a class name so it cannot be accessed by subclasses.

  2. Init and str are strongly typed, you can’t return anything else. The actual constructor is dunder new. Dunder Init is indeed an initializer.

  3. Python should never have get and set methods, ever, for attributes. Rather, use the property() decorator.
