else: print "You missed my battleship!" board[guess_row][guess_col] = 'X' #this line! print_board(board)
well, you should have a multi dimensional array, which should look something like this:
0 1 2 3 4 0 O O O O O 1 O O O O O 2 O O O O O 3 O O O O O 4 O O O O O
i added the numbers of the row an columns. So, lets say i guess 2 for row and 2 for col, you can access this places in the array with board, and update the value from O to X. which is what you do with this line:
board[guess_row][guess_col] = 'X'
board is the variable that holds your multi dimensional array, guess_row is a number (0,1,2,34) and so is guess_col (you prompt the user for the numbers)
Vague question, what do you mean? You can always use array[x][y] to access a certain place in array.
Ok thank very much!
