二十一点 While 循环问题

Question

所以我几乎是在制作一个 21 点模拟器来找出某些手牌获胜或失败的概率。我有一个 while 循环来循环遍历一副完整的 52 张牌，直到剩下 4 张牌。在其中，我有一个 while 循环，让庄家抽牌，直到他的点数达到 17+，就像真正的二十一点一样。当我运行代码时，它将运行成功通过一副牌，但每次只打印同一只手。这是代码：

# <--- PROGRAM SETUP --->
import random

# Drawing Card Function
def draw_card():
    # Card Values in 1 Deck
    vals = [2,2,2,2,3,3,3,3,4,4,4,4,5,5,5,5,6,6,6,6,7,7,7,7,
            8,8,8,8,9,9,9,9,10,10,10,10,10,10,10,10,10,10,10,
            10,10,10,10,10,10,10,10,10,11,11,11,11]
    # </--->

    dealer = 0
    player = 0
    bust = 21


    deck_count = 0
    hand_count = 0

    dealer_cards = []

    # <--- // --->

    cards = 52
    # Loop Hands Through Deck
    while(cards > 4):

        # Draw Card Loop
        while(dealer <= 16):
            card = random.choice(vals)
            vals.remove(card)
            dealer_cards.append(card)

            dealer = dealer + card

        hand_count = hand_count + 1
        cards = cards - len(dealer_cards)


        # <--- Results --->
        if 17 <= dealer <= 21:
            print "Hand: {}, Dealer Stands @ {}".format(hand_count, dealer)
            for i in dealer_cards:
                print "Card: {}".format(i)

        else:
            print "Hand: {}, Dealer Busts @ {}".format(hand_count, dealer)
            for i in dealer_cards:
                print "Card: {}".format(i)

    else:
        deck_count = deck_count + 1
        print "Deck {} is finished!".format(deck_count)

# <--- // --->

draw_card()

当运行我得到：

    Hand: 1, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 2, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 3, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 4, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 5, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 6, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 7, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 8, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 9, Dealer Stands @ 19
Card: 10
Card: 9
Hand: 10, Dealer Stands @ 19
...All the way till the deck has less than 4 cards left.

如何解决才能使每手牌成为唯一的开牌而不是多次打印第一手牌？谢谢

Answer 1

您实际上并没有在循环迭代之间清算庄家的牌。

所以，他可以抽一张牌，因为他到了 19 岁，永远坚持下去，跳过内部 while dealer < 17 循环，并且知道他有一手足够漂亮的牌来骗取你所有的虚拟货币很多。

结果if/else检查后设置dealer = 0即可。

Answer 2

您忘记在每次迭代前重置 dealer 和 dealer_cards，因此您的 while(dealer <= 16): 块在第一次之后将永远不会运行；它只会继续使用相同的分数，但会继续递减 cards.

将您的初始化移动到主 while 循环中：

while(cards > 4):
    dealer_cards = []
    dealer = 0

    # Draw Card Loop
    while(dealer <= 16):
        card = random.choice(vals)
        vals.remove(card)
        dealer_cards.append(card)

        dealer = dealer + card
