Abstract Methods with @abstractmethod
Example
from abc import ABC, abstractmethod
class Shape(ABC):
@abstractmethod
def area(self):
pass
class Circle(Shape):
def __init__(self, r):
self.r = r
def area(self):
return 3.14159 * self.r ** 2
c = Circle(5)
print(c.area()) # 78.54 Pro Tip
ABCs act as interfaces in Python, enforcing contracts on subclasses.
