Can a protected variable be public?

Can protected members be accessed by objects?

How do you access protected methods in Python?

In order to do so, they can inherit the parent class. Python has a unique convention to make a member protected: Add a prefix _ (single underscore).

How can we access protected and private members of a class?

Can a subclass access the private members of its parent?

A subclass does not inherit the private members of its parent class.

A nested class has access to all the private members of its enclosing class—both fields and methods.

How do you inherit protected members in C++?

Protected Inheritance − When deriving from a protected base class, public and protected members of the base class become protected members of the derived class. Private Inheritance − When deriving from a private base class, public and protected members of the base class become private members of the derived class.
