The Ultimate Guide to Python Programming With Python 3.10 - .sort(key) - Sorting Arrays of Class Objects

The video tutorial covers the implementation of a cart system in Python, focusing on sorting products by price. It begins with an introduction to the store package, including product and cart classes. The tutorial then demonstrates how to define a sort method in the cart class, addressing type errors encountered during sorting. A lambda function is used to sort products by their price attribute. The tutorial also includes creating a show method to display sorted products with proper formatting. Finally, it concludes with refining the cart display and ensuring the sorting functionality works as intended.
