[Solved] What will be the output of the following code?class Dog: def sound(self): return "Bark" class Cat: def sound(self): return "Meow" animals = [Dog(), Cat()] for animal in animals: print(animal.sound()) | Python

Python - Polymorphism and Dynamic Behavior

What will be the output of the following code?

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

class Cat:
    def sound(self):
        return "Meow"

animals = [Dog(), Cat()]
for animal in animals:
    print(animal.sound())

AMeow Bark

BBark Bark

CError: sound method not found

DBark Meow

Step-by-Step Solution

Solution:

Step 1: Understand the classes and their methods
Dog and Cat classes both have a method named sound that returns different strings.
Step 2: Trace the loop calling sound on each object
The loop calls sound() on Dog instance (returns "Bark") and Cat instance (returns "Meow"), printing each.
Final Answer:
Bark Meow -> Option D
Quick Check:
Different classes, same method name, different outputs [OK]

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

Common Mistakes:

Assuming both calls return the same string
Expecting a runtime error due to method name
Mixing the order of outputs
