Thanks for your prompt reply! Here's the whole thing:

import random

message = """Welcome to craps!!!! Place your bet
             and roll the dice.
             7 or 11 wins.
             2, 3 or 12 loses.
             Others are "point"."""
player = "Your"
dice = range(1, 7)
stake = 100
bet = 5
winmsg = "You have won!You have ${0} left.".format(stake)
losemsg = "You have lost! You have ${0} left.".format(stake)
players = ["Your", "My"]

def win(num):
    if num in [7,11]:
        return "win"
    elif num in [2,3,12]:
        return "lose"
    else:
        return "point"

def changePlayer(player):
    if player == "Your":
        return "My"
    else:
        return "Your"

def point(num):
    while True:
        raw_input("Roll")

        three = uno+dos

print message

stake)
    bet = int(raw_input("$"))
    stake -= bet
    one, two = random.choice(dice), random.choice(dice)
    print "{0} + {1} = {2}".format(one, two, one+two)
    if win(one+two) == "win":

    elif win(one+two) == "lose":
