Показать описание
Today we're solving the Day 9 Project for 30 Days Of Python. 30 Days Of Python is a free, comprehensive series of blog posts and videos we're publishing over in our blog!

In today's project, we'll implement Luhn's Algorithm for validating whether a card number is likely to be valid or not. Super interesting, and also something that is actually used in the real world!

Remember to try the project first before watching the solution walkthrough, link below!

This is an OUTSTANDING video! It not only shows Python coding but it also gives an insight into what challenges a developer has to address in a real-world situation, not a Hello World example. This video shows that developers must (should) have an understanding of math and problem-solving. Companies do not pay developers to write code; companies pay developers to practically and effectively solve problems with code. This video demonstrates all of that. Again, outstanding. I also notice that you do the same in your tutorials on Udemy. So, thank you.

Hello! I was just wondering what's thr purpose of removing the last digit? Won't we get the same result if we just reverse the if and else statements, then add the processed digits?
