A method marked with @abstractmethod is not defined in the concrete class. This can result in unintended behavior.

It is recommended to implement all abstract methods in the derived classes.

Bad practice

from abc import ABC, abstractmethod

class Vehicle(ABC):

    @abstractmethod
    def start():
        pass

class Car(Vehicle):

    # No overridden `start` method here. Can cause unintended behavior

    def stop():
        self.speed = 0

Recommended

from abc import ABC, abstractmethod

class Vehicle(ABC):

    @abstractmethod
    def start():
        pass

class Car(Vehicle):

    def start():
        self.speed = 3

    def stop():
        self.speed = 0
