The Ultimate Guide to Python Programming With Python 3.10 - Singleton

The video tutorial explains the use of the __new__ and __init__ methods in Python, focusing on how to implement a Singleton pattern. It demonstrates creating a class that allows only one instance using the __new__ method. The tutorial includes testing the implementation with a card example and addresses debugging issues to ensure the Singleton pattern works correctly.

How does the implementation ensure that only one instance of the card is created?

What changes were made to the 'init' method to prevent losing product data when creating a new instance?

Discuss the significance of using a protected variable in the context of the card class.
