Python 21扑克游戏问题

Question

我正在玩21点21点纸牌游戏，但我似乎无法再抽到第三张牌上。再加一张牌，再加上一张牌，再加上一张牌也会发生。在

抱歉，我还是不知道我在做什么。（用这个或Python）

哇。。他们花了一段时间，但我想我终于成功了：）

import random

hand = 0

def draw():
  global hand
  hand = 0

      else:

        print ("not a choice. P.S. I'm too lazy/don't know how to loop this, so you better restart")

    print ("You drew a", card3)

    hand1 = hand + card3

Answer 2

在提供的代码中，print语句表明您正在使用python2，但是各种input()调用似乎是python3。在

我认为您使用的是python2，否则编译器将抱怨并且不会打印任何内容。在

在这种情况下，以pyhton2样式重写输入：

ace1 = int(input("Would you like a 1 or 11?"))

变成：

^{pr2}$

类似于ace2和{}函数中的draw。在python2中，input()已经计算了输入，因此如果输入了一个整数，就已经得到了一个整数。在

draw = input("Would you like to [H]it or [S]tay?")

变成：

draw = raw_input("Would you like to [H]it or [S]tay?")

这可能就是问题所在。input()试着把字符串当作一个变量来处理，当然这是不存在的。在python2中，您需要raw_input()来接受一个字符串作为输入。在

This also happens with the dealer, who just gets stuck in an endless loop of drawing a card, removing the previous card, than adding that card.

我编辑了dealerdraw()来解决这一部分：

def dealerdraw():
    global dealer_cards
    if dealer_cards < 21:
        dealer_card3 = random.randrange(1,12)
        dealer_hand.append(dealer_card3) #add the card to the dealer's list cards
        dealer_cards = sum(dealer_hand) #get the sum of all the cards
        print dealer_hand #just to show that cards in dealer hands are added, remove this line in real game
        print "Dealer drew a card"
        if dealer_cards == 21:
            print "Dealer won"
            print "his hand was", dealer_hand, "totaling", dealer_cards
        elif dealer_cards > 21:
            print "Dealer busted, you won"
            print "his hand was", dealer_hand, "totaling", dealer_cards
        else:
            print "The Dealer smirks"
            print "You're turn"
            print draw()
    elif dealer_cards == 21:
        print "Dealer won, his hand was", dealer_hand, "totaling", dealer_cards
    else:
        print "If you see this, the game isn't working"
    return " "

庄家总是抽一张牌。但现在他手上的牌都加好了，或者他赢了21张，否则他就破产了。由你来改进代码，让经销商留下来。在
