Saying that my variable is not defined


#1



it keeps saying guess_row is not defined. it was working fine until now, all i added was if turn == 3 and now it says guess_row is not defined.


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[0]) - 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!
# Be sure to indent four spaces!
for turn in range(4):
    print(turn + 1)
    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" 
            if turn == 3:
                print ("Game over")
# Print (turn + 1) here!
print_board(board)

Your if statement,

if turn == 3:
                print ("Game over")

should not be nested in your else statement.
