Basic Inheritance, Why Use init

[deanhystad]

A subclass needs __init__ if it needs to initialize attributes that are not inherited from the base class or needs to initialize existing attributes differently.

class Animal():
    varA = "---"
    def __init__(self, name, age, sound='...'):
        self.name = name
        self.age = age
        self.sound = sound
        print(self.name + " has been created")

    def talk(self):
        print(self.name, "Say :", self.sound)

    def myinfo(self):
        print(self.varA + " Info name: " +  self.name + " | Info age: " + str(self.age) + " " + self.varA)
 
class Cat(Animal):
    def __init__(self, name, age):
        super().__init__(name, age, 'Meow')

class Bird(Animal):
    def __init__(self, name, age):
        super().__init__(name, age, 'BrrBrr')
