The Ultimate Guide to Python Programming With Python 3.10 - Classes and Objects - Classes - Inheritence

The video tutorial explains how to create a product class in Python, define attributes and methods, and apply discounts. It introduces the concept of inheritance by creating an ebook class that inherits from the product class, demonstrating how to reuse code and add new features efficiently.

What is the purpose of the '__init__' method in a Python class?

• To define class-level variables

• To apply a discount to a product

• To inherit methods from another class

• To initialize an object's attributes

Which method is used to apply a discount to a product's price?

• apply_discount

• discount_price

• calculate_discount

• set_discount

What is the result of applying a 10% discount to a product priced at 2?

• 1.8

What additional attribute does the 'Ebook' class have compared to the 'Product' class?

• Author

• Pages

• Publisher

• ISBN

How does the 'Ebook' class inherit attributes and methods from the 'Product' class?

• By defining them again in the 'Ebook' class

• By using inheritance with the 'super' function

• By copying and pasting the code

• By using the 'import' statement

What is the purpose of the 'super' function in the context of inheritance?

• To create a new class

• To define a new attribute

• To call methods from the parent class

• To apply a discount

Which of the following is NOT a benefit of using inheritance in Python?
