# There are Two ways to use abstractmethod #

# First Way #

from abc import ABCMeta,abstractmethod

class Dog(metaclass=ABCMeta) :       # Super class #
    @abstractmethod      # Decorator #
    def barking (self) :
        return 0

class BullDog(Dog) : # BullDog class is Inherited by Dog class #
    def barking(self):
        return "Quite/Mild Barking"

class Beagle(Dog) :
    def barking(self):
        return "Loud/Violent Barking"

bulldog = BullDog()
beagle = Beagle()
print(bulldog.barking())
print(beagle.barking())


# Second Way #

from abc import ABC,abstractmethod

from abc import ABCMeta,abstractmethod

class Dog(ABC) :       # Super class #
    @abstractmethod      # Decorator #
    def barking (self) :
        return 0

class BullDog(Dog) : # BullDog class is Inherited by Dog class #
    def barking(self):
        return "Quite/Mild Barking"

class Beagle(Dog) :
    def barking(self):
        return "Loud/Violent Barking"

bulldog = BullDog()
