Abstract Class

Example

from abc import ABC, abstractmethod
class Shape(ABC):
    @abstractmethod
    def area(self):
        pass
    @abstractmethod
    def perimeter(self):
        pass

class Circle(Shape):
    def __init__(self, radius):
        self.__radius = radius
    @staticmethod
    def square(x):
        return x**2
    def area(self):
        return 3.14*self.square(self.__radius)
    def perimeter(self):
        return 2*3.14*self.__radius
c1 = Circle(3.9)
print(c1.area())
