python 从一道作业题到制作一个图形界面的“诈金花”游戏

题目很简单：就是自己写一个程序，实现诈金花游戏的发牌、判断输赢。

规则：

一付扑克牌，去掉大小王，每个玩家发3张牌，最后比大小，看谁赢。

牌型：

豹子：一样大的三张牌，如10,10,10
顺金：又称同花顺，即3张同花色的顺子， 如红桃 5、6、7
金花：又称同花，即3张牌同花色但非顺子，如草花J、8、7
顺子：3张连续大小但花色不全相同，如红桃5、方片6、黑桃7
对子：只有2张一样大的牌，如果对子一样大就比第3张的大小
单张：3张牌不同花不成对也不成顺子，最大的是A带头的单张

版型大小顺序： 豹子>顺金>金花>顺子>对子>单张

从网上百科到的诈金花各种牌型的出现概率，一起放进代码中增加一点趣味小知识。你可能不知道豹子出现的概率比同花顺大，实际打牌时同花顺反而比豹子小；顺子出现的概率比金花小，实际打牌时顺子反而比金花小；最大牌为5、6、7的单张牌型出现的概率都要比金花和顺子小，所以有的地方额外规定同一局中拿到“235”三张牌要比同局的豹子大。

回到正题，直接上代码，主要2个函数：一个计分、一个比大小

from random import shuffle as DealCards
 
Players = 5  #人数
pkPacks = 1  #扑克副数
W = "单张","对子","顺子","金花","顺金","豹子"
X = 74.38, 16.94, 3.26, 4.96, 0.22, 0.24  #出现概率
Y = 0.54, 1.36, 2.44, 3.8, 5.43, 7.33, 9.5, 11.95, 14.66, 17.38 #单张概率
V = *(str(i) for i in range(2,10)),*'TJQKA' #T代表10
F = '♠', '♥', '♣', '♦'
P = [f+v for f in F for v in V]*pkPacks 
 
def Scores(pokers):
    f,p = [],[]
    for poker in pokers:
        f.append(F.index(poker[0])+1)
        p.append(V.index(poker[1])+2)
    t = sorted(p)
    intSame = len(set(t))
    isFlush = int(len(set(f))==1)
    isStraight = t[0]+1==t[1]==t[2]-1
    if intSame==1:
        return 500_0000+t[0] #豹子
    elif intSame==2: #对子一样大比较剩下的单张
        return (100+t[1])*10000+(t[2] if t[0]==t[1] else t[0])
    else: #顺金(同花顺)顺子 else #单张或金花
        return 200_0000*(1+isFlush)+t[2] if isStraight else ((300*isFlush+t[2])*100+t[1])*100+t[0]
 
def WhoWins(P):
    Pokers,Winner = [],[]
    for i in range(0,3*Players,3):
        Pokers.append(P[i:i+3])
    for i,p in enumerate(Pokers,1):
        win = Scores(p)
        idx = win//100_0000
        print(f"Player{i}: {*p,} - {W[idx]}")
        Winner.append(win)
    win = max(Winner) #没有判断“一样大”，如是则谁在前谁为大
    idx = Winner.index(win)
    big = win//10000
    win = big//100
    per = X[win] if win else Y[big-5]
    pok = W[win] if win else '单'+V[big-2]
    print(f"【Player{idx+1} win!】--> {*Pokers[idx],} {pok}({per}%)\n".replace('T','10'))
    return P[3*Players:] #去掉每一局已发的牌
 
if __name__ == '__main__':
    DealCards(P) #以随机洗牌来模拟发牌
    #Players = int(input('请输入参加的人数？'))
    PlayersMax = 52*pkPacks//3+1
    if not 0
        print(f'请注意：参与人数的范围 0 < Players < {PlayersMax} ！')
    else:
        count = 1
        while len(P)>=3*Players: #所有牌(52*PokerPairs)发不够一局为止
            print(f'第{count}局：')
            count += 1
            P = WhoWins(P)

运行结果：

第1局：
Player1: ('♥Q', '♣2', '♣8') - 单张
Player2: ('♦10', '♥7', '♠6') - 单张
Player3: ('♣4', '♠4', '♦2') - 对子
Player4: ('♠5', '♠9', '♥6') - 单张
Player5: ('♠7', '♠3', '♣5') - 单张
【Player3 win!】--> ('♣4', '♠4', '♦2') 对子(16.94%)

第2局：
Player1: ('♥2', '♥8', '♦4') - 单张
Player2: ('♦9', '♦3', '♥A') - 单张
Player3: ('♠J', '♣A', '♦K') - 单张
Player4: ('♠8', '♥9', '♥10') - 顺子
Player5: ('♣7', '♣9', '♣10') - 金花
【Player5 win!】--> ('♣7', '♣9', '♣10') 金花(4.96%)

第3局：
Player1: ('♦7', '♦J', '♠2') - 单张
Player2: ('♥J', '♦A', '♥K') - 单张
Player3: ('♥4', '♥5', '♦6') - 顺子
Player4: ('♣Q', '♣J', '♠10') - 顺子
Player5: ('♣K', '♦8', '♦5') - 单张
【Player4 win!】--> ('♣Q', '♣J', '♠10') 顺子(3.26%)

【扩展】学习要举一反三，做完题目想到把这个程序的界面图形化。为方便摆放牌堆，就只指定一付扑克四个玩家。然后，无非就是把原代码中扑克牌对应花色、大小的下标值从以下牌型图中索引出相应的图来，放到对应的Image控件上；而想要输出的文字就对应到text控件上；再整几个button控件绑定对应的事件动作，就搞定了！

Windows的Cmd窗口中执行如下命令，Mac系统自行百度对应的编译命令：

pyinstaller -F exam.py --noconsole
