Python Programming: Lesson 38 - Private Variables
PLEASE SUBSCRIBE!!!
In the previous lesson ( • Python Programming: Lesson 37 - Garba... ), we reviewed dunders and investigated ways to treat an instance of a class as though it were an iterable. In this lesson, we review dunders and instance methods, although we continue our discussion to include strongly and weakly private instance variables. Not much new content here, just a 6th opportunity to see OOP concepts. Only two more OOP videos after this one, and only six videos total.
A weakly private instance variable has one underscore between self. and the name of the instance variable. It is discouraged from being used outside of the class in which it is defined. A strongly private instance variable has two underscores between self. and the name of the instance variable. It cannot be used outside the class in which it is defined.
