The instructions are unclear in a couple regards:
1) After your new if: statement, add an else: that contains your existing handler for an incorrect guess.
- I don't know what a handler is, but if I add the existing code for an incorrect guess again, it is then printed on-screen twice instead of once.
2) (Hint): "The valid values for guess_row are 0 to rows-1 and the valid values for guess col are 0 to cols-1. You will need to build up a complex Boolean expression of the form:"
- The example of a "complex Boolean expression" is missing from the hint. I have AdBlocker paused and the codecademy domain is whitelisted in Ghostery, so it seems the information is simply not there.
