Python does not have declarations. Many people view that as an
advantage, since having to declare variables before first use (or
perhaps even after first use?) requires a lot of boilerplate code that
contributes little to the meaning of the program.

If you have accepted that you don't have to declare local variables in
a function (it isn't clear from your article whether you have): Why
would you require to declare instance attributes?
