Inheritance in OOP | Lecture 17 | Python Course For Beginners
Welcome to Lecture 17 of our 'Python for Beginners' series! In this video, we dive into the fascinating concept of Inheritance in Object-Oriented Programming (OOP). You'll learn the fundamental definitions, explore various operations, and engage in hands-on coding activities to solidify your understanding.
In this lecture, we cover:
The basics of inheritance in Python
How to define parent and child classes
Using the super() function to call parent class methods
Practical coding activities to apply what you've learned
*Practice Questions:
1-Create a class Animal with a method sound(). Create a subclass Dog that overrides the sound() method.
2-Define a Vehicle class with attributes brand and model, and a method description(). Create a subclass Car that adds an attribute fuel_type and overrides the description() method to include fuel_type.
3-Implement a Person class with attributes name and age. Create a subclass Student that adds an attribute grade and a method student_info() that prints all attributes.
4-Create a Shape class with a method area(). Create subclasses Square and Circle that override the area() method to calculate the area of a square and a circle, respectively.
5- Define a Bird class with a method fly(). Create a subclass Penguin that overrides the fly() method to indicate that penguins can't fly.
*Quiz Question:
Which of the following is true about inheritance in Python?
a) A class can only inherit from one parent class.
b) Inherited methods cannot be overridden.
c) The super() function is used to call the parent class constructor.
d) A child class can access private members of the parent class.
