Just a note from a learner's perspective:
The "Tip" introduces the idea of using a for loop without demonstrating how to do that. I understand that you might want to use a for loop to iterate over more than one piece of data but I have no idea how to implement that based on the example above.

It would be great to see how that would be implemented underneath the "Tip"!
