So my code works to an extent but there is a slight problem. The user input starts at the 3rd column instead of the first. So if I were to input row 1 and column 4, it would output row 3 and column 4.


I'm pretty sure it's not supposed to that and it's supposed to start from the first column.


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):
    guess_row = int(raw_input("Guess Row:"))
    guess_col = int(raw_input("Guess Col:"))
    
    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"
        print "Turn", turn + 1
        print_board(board)

well, our board is a list, lists start counting at zero, while we humans start counting at one. Its not in the scope of the exercise to address this problem, but its a good challenge. Tip: its easier to manipulate user input then list indexes
