Ceora Ford: [0:01] Working from my_tuple, we're going to try to add another item to the end of this tuple. We'll do this by using the append() method. I'm going to append a list of my favorite foods which includes pizza, lasagna, and cookies.

[0:30] As you can see, we get an error. This is because tuples are immutable which means that after they've been created, we cannot change or alter them. There is a way to get around this though if you really want to add a new item into your tuple.
