What’s the point of inheritance in Python?

Question

Suppose you have the following situation

#include 

class Animal {
public:
    virtual void speak() = 0;
};

class Dog : public Animal {
             


        

Answer 1

Another small point is that op's 3'rd example, you can't call isinstance(). For example passing your 3'rd example to another object that takes and "Animal" type an calls speak on it. If you do it don't you would have to check for dog type, cat type, and so on. Not sure if instance checking is really "Pythonic", because of late binding. But then you would have to implement some way that the AnimalControl doesn't try to throw Cheeseburger types in the truck, becuase Cheeseburgers don't speak.

class AnimalControl(object):
    def __init__(self):
        self._animalsInTruck=[]

    def catachAnimal(self,animal):
        if isinstance(animal,Animal):
            animal.speak()  #It's upset so it speak's/maybe it should be makesNoise
            if not self._animalsInTruck.count <=10:
                self._animalsInTruck.append(animal) #It's then put in the truck.
            else:
                #make note of location, catch you later...
        else:
            return animal #It's not an Animal() type / maybe return False/0/"message"
