[Solved] Find the error in this code that tries to override a method:class Parent: def show(self): print('Parent show') class Child(Parent): def show(): print('Child show') obj = Child() obj.show() | Python

Python - Polymorphism and Dynamic Behavior

Find the error in this code that tries to override a method:

class Parent:
    def show(self):
        print('Parent show')

class Child(Parent):
    def show():
        print('Child show')

obj = Child()
obj.show()

AMissing self parameter in Child's show method

BParent class method show is private

CChild class should not override show method

Dobj.show() should be called as Child.show(obj)

Step-by-Step Solution

Solution:

Step 1: Check method signature in Child class
The Child's show method is missing the 'self' parameter, so it is not a proper instance method.
Step 2: Understand impact of missing self
Calling obj.show() will cause a TypeError because Python expects the first argument (self) but none is defined.
Final Answer:
Missing self parameter in Child's show method -> Option A
Quick Check:
Instance methods must have self parameter [OK]

Quick Trick: Instance methods always need self as first parameter [OK]

Common Mistakes:

Ignoring missing self parameter
Thinking method overriding is not allowed
Believing calling method differently fixes error
