Python - Object-Oriented Programming - Using A Class Inside Another Class

This video tutorial covers the basics of object-oriented programming in Python, focusing on creating and using classes and objects. It provides a practical example of a shopping list application, demonstrating how to define a Product class with attributes and methods, and a Shopping List class that incorporates Product objects. The tutorial includes step-by-step instructions for implementing and testing these classes, emphasizing the importance of understanding object interactions and validating inputs.

What is the primary purpose of using objects within other objects in programming?

• To increase the complexity of the code

• To make the code run faster

• To enable objects to interact and work together

• To allow objects to work independently

Which of the following is an attribute of the Product class?

• Title

• Brand

• Color

• Price

What method is used to change the quantity of a product in the Product class?

• update_quantity

• set_quantity

• modify_quantity

• change_quantity

What is the initial state of the items attribute in the ShoppingList class?

• A list with a default quantity

• A list with a default title

• An empty list

• A list with one default item

Which method in the ShoppingList class is responsible for adding a new product?

• insert

• add

• include

• append

What happens if a non-product item is added to the shopping list?

• It is added without any issue

• An error is thrown

• The program crashes

• A message is printed indicating it's not a product

What is the purpose of the show method in the ShoppingList class?

• To remove items from the list

• To sort the items alphabetically

• To print all products in the shopping list

• To display the total price of items
