Let's consider one of the 3 pillars of OOP - encapsulation, see what it is and what is better not to expect.

Encapsulation implies collecting data and methods for working with them in one place (class), as well as providing a public interface (API) for working with them.

In Python, the underscore _ is used to mark the internal implementation, that is, attributes that are not related to the public interface.

One underscore (protected) is just a signal, the interpreter treats such attributes as ordinary ones.
Two underscores (private) - includes the Name Mangling mechanism, which is not intended to hide data.

Encapsulation in Python does not imply hiding data (in some languages, this is the same thing) - all data is available for viewing and changing. In Python, we do not try to take away tools from the user, we warn.
