Answer 1

Because you don't really have a local or global screen variable.
You declare self.screen, and this is a class field.
Unlike many other languages, python requires self to be explicit when accessing class fields from its methods, and does not allow them to be accessed as local variables.
So further in the Ship methods you will have to use self.screen.
