How to copy python code properly?


Well I want to copy this into python so I can have it as a .py file but when I paste it into IDLE 3.5 (32 bit) it says unknown syntax on loads of things. What do I do so I can save it as .py and show it to my teacher as a file on its own?

I expected it to just work like it did in the website.

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):
    print "Turn", turn + 1

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


codecademy runs python2.7.3, and python3 is not backward compatible.

in this code, there are two changes you need to make, in python2 print was a keyword, where as in python3 it is a function call which means parentheses are required:

print("parentheses required")

and in python3 raw_input() no longer exist, this is now input()


Thanks! Im going to change it now, I can always count on good response and how quick you guys reply.
