Finished this lesson but "already guessed" message doesn't appear


#1

Greetings.
I've just finished "Battleship". Codecademia passed it as correct, but I found that "already guessed" message doesn't appear when it must. Please, would you help me to fix this bug?
Thank you.

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[0]) - 1)

    ship_row = random_row(board)
    ship_col = random_col(board)
    
    
for turn in range(4):
    
    guess_row = int(raw_input("Guess Row:"))
    guess_col = int(raw_input("Guess Col:"))

    print ship_row
    print ship_col

    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, that's not even in the ocean."
         
    elif guess_row == "X" and 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
        
    if turn == 3:
        print "Game Over"
    
        
print print_board(board)

the user isn't going to guess "X", you need to change it the the same as the else statement in comparing:

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