Basic Inheritance, Why Use init

[udinjelek]

I'm new in Programing Language.

in here Bird and Cat are inheritance from Animal,
- Bird use __init__ and super
- Cat use nothing

but both have good result, inheritance from animal, the function work perfectly
is there explanation why we still use __init__ super since without it, inheritance still working and less code

Thanks

class Animal():
    varA = "---"
    def __init__(self,name,age):
        self.name = name
        self.age = age
        print(self.name + " has been created")
    def talk(self):
        print(self.name + "Say : ...")
    def myinfo(self):
        print(self.varA + " Info name: " +  self.name + " | Info age: " + str(self.age) + " " + self.varA)


class Cat(Animal):
    def talk(self):
        print(self.name + " Say: Meow")
 
 
class Bird(Animal):
    def __init__(self,name,age):
         super().__init__(name,age)     
    def talk(self):
        print(self.name + " Say: BrrrBrr")


print("------------------------------")
randomAnimal = Animal("randomAnimal",9)    
randomAnimal.talk()
randomAnimal.myinfo()
print("------------------------------")
blackCat = Cat("BlackCat",2)
blackCat.talk()
blackCat.myinfo()
print("------------------------------")
blueBird = Bird("BlueBird",3)
blueBird.talk()
blueBird.myinfo()
print("------------------------------")

Result Code:

------------------------------
randomAnimal has been created
randomAnimalSay : ...
--- Info name: randomAnimal | Info age: 9 ---
------------------------------
BlackCat has been created
BlackCat Say: Meow
--- Info name: BlackCat | Info age: 2 ---
------------------------------
blueBird has been created
blueBird Say: BrrrBrr
--- Info name: BlueBird | Info age: 3 ---
------------------------------
