Please someone help


#2

The error is due to the fact that you are doing the wrong way, at line 32, when you want to put a X at the row/column in your board. board is a matrix, so in order to access the correct combination of column/row, you need to write

board[guess_row][guess_col]="X"

instead of

board[guess_row]="X"
board[guess_col]="X"

Moreover, you need to rearrange your if / elif :

if (guess_col == ship_col and guess_row == ship_row):
   print "Congratulations! You sank my battleship!"
else:
   if guess_col not in range(len(board) - 1) or guess_row not in range(len(board) - 1):
        print "Oops, that's not even in the ocean."
    elif board[guess_row][guess_col]=="X":
        print "You guessed that one already."
    else:                                    # <-- NEW
        print "You missed my battleship!"
        board[guess_row][guess_col]="X"
        print_board(board)
