Polymorphism in Python Question

[hshivaraj]

There is no concept on interface in python. However you can define an abstract class. And you do this by inheriting from class called ABC. See the link bellow to know more about ABC.

https://docs.python.org/2/library/abc.html

class Animal(ABC):

    def __init__(self):
        super.__init__()

    @abstractmethod
    def sound(self):
        pass


class Dog(Animal):

    def __init__(self):
        pass

    def sound(self):
        return "Im dog"
