__init__ runs when you create an object.

self refers to the object the method is called on.

Solution explanation

A class is a blueprint; each object (instance) has its own attribute values.

class Dog:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def bark(self):
        return f"{self.name} says woof!"


dog = Dog(input(), int(input()))
print(dog.bark())
print(dog.age * 7)
