Oops, try again. Make sure you print "Oops, that's not even in the ocean." if the user guesses a row or column that is off the board.
Replace this line with your code. from random import randint board =  for x in range(0, 5): board.append(["O"] * 5) def print_board(board): for row in board: print " ".join(row) print_board(board) def random_row(board): return randint(0, len(board) - 1) def random_col(board): return randint(0, len(board) - 1) ship_row = random_row(board) ship_col = random_col(board) guess_row = int(raw_input("Guess Row:")) guess_col = int(raw_input("Guess Col:")) print ship_row print ship_col # Write your code below! if (guess_row == ship_row) and (guess_col == ship_col): print "Congratulations! You sank my battleship" elif (guess_row not in range(5)) or (guess_col not in range(5)): print "Oops, thats not even in the ocean!" else: print "You missed my battleship!" board[guess_row][guess_col] = "X" print_board(board)
