I'm getting this error message "Did you remember to add the "You guessed that one already." message in your elif statement?" also, is there for the second battleship board to be like the first 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 if ship_row == guess_row & ship_col == guess_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 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 board
