Day 16 of My AI & Data Mastery Journey: From Python to Generative AI

Inheritance

🧠 Concept:

Child class inherits data + behavior from parent class.

💼 Real-world idea:

A Manager is an Employee but with extra privileges.

Creation Question

Create a base class Employee with attributes name, salary.
Create subclass Manager(Employee) with extra attribute department.
Add a method show_info() showing all details.

Debugging Question

class Vehicle:
    def move(self):
        print("Moving")

class Car(Vehicle):
    def wheels():
        print("4 wheels")

c = Car()
c.move()
c.wheels()

🎯 Bug: parameter error in subclass method.

** Polymorphism**

🧠 Concept:

Same function name, different behavior per class.

💼 Real-world idea:

Payment method — can be through CreditCard, UPI, or Cash.

Creation Question

Create 3 classes:
CreditCard, UPI, and Cash — each with a pay(amount) method showing how payment is made.
Then loop through all and call .pay() — observe polymorphism.

Debugging Question

class Dog:
    def speak(self):
        print("Woof!")

class Cat:
    def speak():
        print("Meow!")

for pet in [Dog(), Cat()]:
    pet.speak()

🎯 Bug: missing argument in one class’s method definition.
