i really dont get why its showing this
Oops, try again. Your code looks a bit off. Check the Hint if you need help! Your code threw the following error: invalid literal for int() with base 10: ''
It looks correct i dont understand why it doesn't work
Replace this line with your code. from random import randint board =  for x in range(5): board.append(["O"] * 5) def print_board(board): for row in board: print " ".join(row) print "Let's play Battleship!" 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) print ship_row print ship_col # Everything from here on should go in your for loop! for turn in range(4): guess_row = int(raw_input("Guess Row:")) guess_col = int(raw_input("Guess Col:")) if guess_row == ship_row and guess_col == ship_col: print "Congratulations! You sunk my battleship!" else: if (guess_row < 0 or guess_row > 4) or (guess_col < 0 or guess_col > 4): print "Oops, that's not even in the ocean." elif(board[guess_row][guess_col] == "X"): print "You guessed that one already." else: print "You missed my battleship!" board[guess_row][guess_col] = "X" print "Turn",turn + 1 print_board(board)
