Python - Polymorphism and Dynamic Behavior

What will be the output of this code?

class Bird:
    def sound(self):
        return "Chirp"

class Dog:
    def sound(self):
        return "Bark"

def animal_sound(animal):
    return animal.sound()

print(animal_sound(Bird()))
print(animal_sound(Dog()))

ABark\nChirp

BChirp\nBark

CError: sound method missing

DNone\nNone

Step-by-Step Solution

Solution:

Step 1: Understand polymorphism in the code
Both Bird and Dog classes have a sound() method. animal_sound calls sound() on any object passed.
Step 2: Trace the print statements
animal_sound(Bird()) returns "Chirp"; animal_sound(Dog()) returns "Bark"; prints are in that order.
Final Answer:
Chirp\nBark -> Option B
Quick Check:
Polymorphism output = Chirp then Bark [OK]

Quick Trick: Same method name, different classes, different outputs [OK]

Common Mistakes:

Assuming method names must be different
Expecting errors due to different classes
Confusing order of print statements
