Battleship program not working in terminal


My battleship program works just fine in the web browser;
however, it will not run in terminal. Can anyone point out
why? I cannot figure this out for the life of me.

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)
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
        if turn == 3:
            print "Game Over"


what python version does your IDLE run?

for python3, print requires parentheses because its a function call where it used to be a statement in python2

and raw_input is now input
