Classes are great if you need to keep state, because they containerize data (variables) and behavior (methods) that act on that data and should logically be grouped together. This leads to code that is better organized (cleaner) and easier to reuse.

What is __ init __ in python?

It can modify a class state that would apply across all the instances of the class.

What is a member variable in Python?

In object-oriented programming, a member variable (sometimes called a member field) is a variable that is associated with a specific object, and accessible for all its methods (member functions).
