Method super()

To call the parent's class method instead of the current one, we use the_super()_method in Python.

Code

We create the Cat object. The super() method inside the Cat object refers to the parent's class Animal. So Animal constructor is called first.

Afterward, go back to the Cat constructor, initialize the age attribute and print the message.


              123456789101112
            
class Animal:
  def __init__(self, name):
    print('Calling Animal constructor')
    self.name = name

class Cat(Animal):
  def __init__(self, name, age):
    super().__init__(name)
    self.age = age
    print('Calling Cat constructor')

cat = Cat('Archie', 12)

Tutto è chiaro?
