But, for example, C++ has 3 categories of object attributes. Do you mark
them somehow in Python, group them to be later marked as public,
protected, private? And there are lot's of details like this one.

Related topic is UML with Python. Does UML has everything to reflect
Python OO model or does it need to add features?
(Or maybe in order to interoperate, there is a need not to use some
of Python features).

And if in order to interoperate with less expressive languages/systems,
how to keep Python pythonic and not fall back to some standard universal
subset, found in many programming languages.
