Why is there an undefined letter in these loop problems?

When there is a loop being printed here, it looks like they are assigning a random letter to the loop when the print () function comes up. I don't see the letter being identified, is it being identified in value by the "if"?

It would be easier to help if you could edit your question to show an example.
