I don't know how to do this:

Set the list element at guess_row, guess_col to "X".
As the last line in your else statement, call print_board(board) again so you can see the "X".

Hint
To specify a single element in a 2-dimensional list, you need to give two indices. The syntax is: list_name[i][j], where i is an element in the outer list and j is an element in the inner list.

Even with the hint I don't get it. This is my 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[0]) - 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_row == ship_col:
    print "Congratulations! You sank my battleship!"
else:
    print "You missed my battleship!"
    ?????????/
    print_board(board)

I tried this now:

else:
print "You missed my battleship!"
board[guess_row][guess_col] == "X"
print_board(board)

But I got this error:

Oops, try again. It looks like your game does not change the O to a capital X for an incorrect guess.

you need to use one equal sign because you are not comparing, you're assigning
i haven't really looked through your code so i don't know if that's the only problem, but that's the first thing that i saw.

Yes, it worked! Thankyouuu
