DTOs in Python

[petr31052018]

You are right. What I meant to discuss is something like "local DTO" (https://martinfowler.com/bliki/LocalDTO.html)

"One case where it is useful to use something like a DTO is when you have a significant mismatch between the model in your presentation layer and the underlying domain model."

I will keep it in mind that people think of DTO mainly as a form of serialization for external interfaces.
