Why multiple inheritance exists in Python - See It in Action

Understanding Why Multiple Inheritance Exists in Python

📖 Scenario: Imagine you are building a simple program to model different types of vehicles. Some vehicles can fly, some can float on water, and some can do both. To represent these abilities, you will use Python classes.

🎯 Goal: You will create classes to represent flying and floating abilities, then create a new class that inherits both abilities using multiple inheritance. This will help you understand why multiple inheritance exists and how it can be useful.

📋 What You'll Learn

Create a class called Flyer with a method fly() that prints 'Flying high!'

Create a class called Floater with a method float() that prints 'Floating on water!'

Create a class called FlyingBoat that inherits from both Flyer and Floater

Create an object of FlyingBoat and call both fly() and float() methods

Print the outputs of both methods

💡 Why This Matters

🌍 Real World

In real life, many objects or roles combine multiple abilities. For example, a smartphone can make calls, take pictures, and play music. Multiple inheritance helps model such combined abilities in programming.

💼 Career

Understanding multiple inheritance is important for software developers to design flexible and reusable code, especially when working with complex systems that combine different features.

1

Create the Flyer class

Create a class called Flyer with a method fly() that prints the text 'Flying high!'

Python

# Your code here

Need a hint?

Use the class keyword to create a class and define a method inside it.

2

Create the Floater class

Create a class called Floater with a method float() that prints the text 'Floating on water!'

Python

class Flyer:
    def fly(self):
        print('Flying high!')

# Your code here

Need a hint?

Define another class similar to Flyer but with a different method.

3

Create the FlyingBoat class using multiple inheritance

Create a class called FlyingBoat that inherits from both Flyer and Floater

Python

class Flyer:
    def fly(self):
        print('Flying high!')

class Floater:
    def float(self):
        print('Floating on water!')

# Your code here

Need a hint?

Use parentheses to list both parent classes when defining FlyingBoat.

4

Create an object and call both methods

Create an object called fb of class FlyingBoat. Then call fb.fly() and fb.float() to print both messages.

Python

class Flyer:
    def fly(self):
        print('Flying high!')

class Floater:
    def float(self):
        print('Floating on water!')

class FlyingBoat(Flyer, Floater):
    pass

# Your code here

Need a hint?

Create an object and call both methods to see how multiple inheritance allows access to both.
