21点，不会用python重新启动游戏

Question

现在重新启动代码时遇到问题。它会重新启动，但不会回到开始。它总是问我要不要重新开始。在

例如它说

The player has cards [number, number, number, number, number] with a total value of (whatever the numbers add up too.)

--> Player is busted!

Start over? Y/N

我输入Y，它一直在说

The player has cards [number, number, number, number, number] with a total value of (whatever the numbers add up too.)

--> Player is busted!

Start over? Y/N

谁能修好它，让它重新启动吗。-或者告诉我我的代码在下面。在

from random import choice as rc

# This function returns True if the player wants to play again, otherwise it returns False.
print('Do you want to play again? (yes or no)')
return input().lower().startswith('y')

有趣的小游戏，我删除了第二个经销商为简单，但它应该很容易添加回来。我将input改为raw_input，这样您就可以从中获取一个字符串，而不必输入引号。对逻辑进行了一些修改，重新设置格式并添加了注释。在

from random import choice as rc

def play_again():
    """This function returns True if the player wants to play again,
    otherwise it returns False."""
    return raw_input('Do you want to play again? (yes or no)').lower().startswith('y')

def total(hand):
    """totals the hand"""
    #special ace dual value thing
    aces = hand.count(11)
    t = sum(hand)
    # you have gone over 21 but there is an ace
    while aces > 0 and t > 21:
        # this will switch the ace from 11 to 1
        t -= 10
        aces -= 1
    return t
