Explanation / Answer

1)Objects are key to understanding object oriented terminology.

->Generally objects related to real world entity.

->real world entity we consider as object.for which we can say state as well as behaviour

->consider human as object which have state like height,weight,colour etc.

    ->behaviour like talking,walking etc.

in our programming language we can define object as instance of class: for suppose i defined human as class

then take one instance of that human class i.e,you or someone.which give all information regarding you or someone.

->Here states like data members,behaviour like methods .

2)in given example : 1)arguments passing :we must include 'self' as one argument.

                                2)variable definition in constructors

def _init_(self,initial_x,initial_y):

            self.x=initial_x

            self.y=initial_y
