Play it, Sam - help needed!


I am stuck with adding in the different turns using a for loop to iterate through the code - please help!

I'm getting the error message,"invalid syntax" - can someone point out where I'm going wrong and how I can rectify the problem.

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

for turn in range(3):
    print: turn
        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 + 1
    print: turn + 2
    print: turn + 3


since when do we need a colon after a print keyword?


Thank you.. must've been coding with tired eyes!
