[Solved] What will be the output of the following code?class Bird: def fly(self): print('Flying') class Airplane: def fly(self): print('Jet flying') objects = [Bird(), Airplane()] for obj in objects: obj.fly() | Python

Python - Polymorphism and Dynamic Behavior

What will be the output of the following code?

class Bird:
    def fly(self):
        print('Flying')

class Airplane:
    def fly(self):
        print('Jet flying')

objects = [Bird(), Airplane()]
for obj in objects:
    obj.fly()

AFlying\nJet flying

BJet flying\nFlying

CFlying\nFlying

DError: fly method not found

Step-by-Step Solution

Solution:

Step 1: Understand the objects and their fly methods
Bird has fly() printing 'Flying', Airplane has fly() printing 'Jet flying'.
Step 2: Trace the loop calling fly on each object
First object is Bird(), prints 'Flying'. Second is Airplane(), prints 'Jet flying'.
Final Answer:
Flying\nJet flying -> Option A
Quick Check:
Each object's fly() runs in order [OK]

Quick Trick: Each object's method runs in loop order [OK]

Common Mistakes:

Assuming type matters for method call
Mixing output order
Expecting error due to different classes
