为什么在某些情况下python变量不显示

我正尝试在python中制作二十一点,但是当计算机获胜时,它无法正常工作,我无法理解为什么。这是我的代码:

import random

hand = []
chand = []
bust = 'no'
sit = 'no'
value = 0
ais = 0
play = 'yes'
x = 0
cards = {
        'a': 11,
        '2': 2,
        '3': 3, 
        '4': 4,
        '5': 5, 
        '6': 6, 
        '7': 7,
        '8': 8,
        '9': 9,
        '10': 10,
        'j': 10,
        'q': 10,
        'k': 10, 
        }



print('''welcome to black jack
type draw or sit to get started''')
while x < 2:
        cardc = random.choice(list(cards.keys()))
        hand.append(cardc)
        x = x + 1
print('your cards', ', '.join(hand))
while bust != 'yes' and sit != 'yes':
        player = input('what would you like to do: ')
        if player == 'draw':
                cardc = random.choice(list(cards.keys()))
                hand.append(cardc)
                print('your cards', ', '.join(hand))
                value = 0
                for i in hand:
                        value = value + cards[i]
#                print(value)
                if value > 21:
                        bust = 'yes'
        elif 'sit' in player:
                print('you have sat')
                sit = 'yes'
if 'yes' in bust:
        print ('you lose')



if sit == 'yes':
        while ais < value and ais < 21:
                cardc = random.choice(list(cards.keys()))
                chand.append(cardc)
                ais = 0
                for i in chand:
                        ais = ais + cards[i]
                        print(ais)

        if ais > 21:
                print('my score was', ais)
                print('you win')
        else:
                print('my score was', ais)
                print('you lose')

当计算机获胜时,本来是要显示计算机卡,但只是显示空白,而当玩家获胜时,则要显示计算机卡。 我对python很陌生,可能会遗漏一些明显的东西,但我不知道为什么会出错

答案 0 :(得分:1)

while ais < value and ais < 21:

是您面临的问题。如果ais == value永远不会运行,那么发牌者就不会抓牌。

您需要使用;

while ais <= value and ais < 21:

此外,这与您在此处遇到的问题有关;

if ais > 21:
    print('my score was', ais)
    print('you win')
else:
    print('my score was', ais)
    print('you lose')

您只检查庄家的手牌是否超过21张。您不检查是否有开奖(这会造成损失)。

如果玩家没有抓牌,您也不会设置值,这意味着即使用户比发牌者得分更高,如果玩家没有抓牌,发牌者也将永远获胜。
