13/19 Odd syntax error that I can't find


So, i'm running into the problem that in my line
if guess_row == ship_row and guess_col == ship_col:
the interpreter is tripping on the last letter of guess_col for some reason. I've tried retyping, reloading, and wrapping things in parens. Nothing seemse to be working. Anyone see my problem?

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)


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)
guess_row = 0
guess_col = 0

def guess():
    guess_row = int(raw_input("Guess Row:"))
    guess_col = int(raw_input("Guess Col:"))

print ship_row
print ship_col

def update_board(x,y):
    board[x][y] = "X"
def repeat_check():
    currentGuess = [guess_row, 

if guess_row == ship_row and guess_col == ship_col:
    print "Congratulations! You sank my battleship!"
    if 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."
        update_board(guess_row, guess_col)
        print "You missed my battleship!"


What is going on with this unfinished bit of code?
