Python - Object-Oriented Programming - Assignment 2

The video tutorial explains how to create a shopping list class in Python. It covers the use of attributes, an alternative constructor using a string, and provides an exercise for viewers to try creating the class themselves. The tutorial then demonstrates the implementation of the class, including the init method and a class method for handling string input. Finally, it shows how to test the class by creating shopping list objects and printing their items.

What is the purpose of the 'from a string' method in the shopping list class?

• To delete items from the shopping list

• To print the items in the shopping list

• To create a shopping list from a string of items

• To convert a list of items into a string

What should you do after pausing the video as instructed?

• Create a shopping list using a dictionary

• Write a function to sort the shopping list

• Attempt to create a class with the described behavior

• Design a user interface for the shopping list

Which decorator is used to define the 'from a string' method as a class method?

• @staticmethod

• @abstractmethod

• @property

• @classmethod

How can you create a shopping list object using a string of items?

• By using the 'from a string' method

• By using a static method

• By directly assigning the string to the items attribute

• By converting the string to a list manually

What is demonstrated at the end of the video?

• That both methods of creating a shopping list result in the same items

• How to add new items to the shopping list

• How to delete items from the shopping list

• How to sort the shopping list alphabetically
