What is the function of "self"?

Answer

“Self” is a variable that represent the instance of the object to itself. In most of the object oriented programming language, this is passed as to the methods as a hidden parameters that is defined by an object. But, in python it is declare it and pass it explicitly. It is the first argument that gets created in the instance of the class A and the parameters to the methods are passed automatically. It refers to separate instance of the variable for individual objects. This is the first argument that is used in the class instance and the “self” method is defined explicitly to all the methods that are used and present. The variables are referred as “self.xxx”.
