Why do we need self in Python?
The self is used to represent the instance of the class. With this keyword, you can access the attributes and methods of the class in python. It binds the attributes with the given arguments. The reason why we use self is that Python does not use the ‘@’ syntax to refer to instance attributes.
What is if name == Main in Python?

Should I use classes in Python?
Whenever you need to maintain a state of your functions and it cannot be accomplished with generators (functions which yield rather than return). Generators maintain their own state. If you want to override any of the standard operators, you need a class.
What is __ init __ Python?

Can __ init __ return value python?
__init__ method returns a value The __init__ method of a class is used to initialize new objects, not create them. As such, it should not return any value. Returning None is correct in the sense that no runtime error will occur, but it suggests that the returned value is meaningful, which it is not.
