(To Your Battle Stations!) Out of range, still stuck



After guessing a coordinate that is outside of the board range and after printing "Oops, that's not even in the ocean." I get an error message:

Traceback (most recent call last):
File "python", line 42, in
IndexError: list assignment index out of range

Of course, I want the game to proceed and I can't tell why it doesn't. Everything else works as it should.

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!"

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!"
        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."
            print "You missed my battleship!"
        board[guess_row][guess_col] = "X"
    print "Turn", (turn + 1)# Print (turn + 1) here!
if turn == 3:
    print "Game Over"
