Basic Battleship

So this was my first coding project and I basically had no idea what I was doing. So I found an old video on how to make a game. So I did. I changed a few things. Made it to where the ships location wouldn’t print, but left the functionality in the code if it is needed for later. One thing I was not sure how to do was keep the program from instantly closing on the last turn. Also some pointers on how to make the ship two spaces big instead of just one would be appreciated.
