Is there a reason why Craig left the "TODO" on the program for credit card info?
I'm assuming that the "TODO" for this was left "TODO" because it's beyond the scope of what Craig was going through in this lesson, correct?

Correct. The specifics on working with credit card information processing can be very complicated. Not necessarily from a python language standpoint but rather from intricate details that wouldn't really add to the overall lesson. So Craig left this as a TODO.
