C++/Java class variables can be public, protected (accessible to class and subclasses) or private (accessible only to class). Of course the language protections can be hacked around.
Python does conceptual private variables by using the single underscore: object._myvar is considered private From: Python-list <python-list-bounces+gweatherby=uchc....@python.org> on behalf of Alan Gauld <learn2prog...@gmail.com> Date: Thursday, November 3, 2022 at 6:45 AM To: Julieta Shem <js...@yaxenu.org>, python-list@python.org <python-list@python.org> Subject: Re: an oop question *** Attention: This is an external email.

Python doesn't do any form of data protection/hiding. All attributes are public by default. In Smalltalk all attributes are private, with no way to make them public... Actually in C++/Java terms I believe they are "protected" because subclasses can access them(I think?). -- https://mail.python.org/mailman/listinfo/python-list
