It is best to set initial values to attributes of an instance object in the __init__() method. class Animal(object): def __init__(self, name): self.name = name. The __init__() method doesn't have to return a value. Of course it can if you like, but Python will just ignore the __init__ is a special Python method (also called dunder method) that is automatically called when memory is allocated for a new object. As it quickly became tiresome to say under-under-method-under-under Pythonistas adopted the term “dunder methods”, a short form of “double under.” Then, it calls class A's __init__ function with *args.

The program runs fine but nothing is printed. c. class Point: def __init__(self, x, y): self._x = x self._y = y The __init__ method gets called when memory for the object is allocated: x = Point(1,2) It is important to use the self parameter inside an object’s method if you want to persist the value with the object. If, for instance If a class implements the __str__ method, Python will call the __str__ method when you pass an instance of the class to the str (). For example: class Person: def __init__(self, first_name, last_name, age): self.first_name = first_name self.last_name = last_name self.age = age def __repr__(self): return f'Person ("{self.first_name}","{self.
