关于21点玩法我想说打扑克嘛？Python教你“经典纸牌游戏21点”玩法

门

昨天不是星期天吗？

你们在家放松的话一般做什么？

周末购物，出去看电影。这是你们的周末。

程序员的周末就是在家躺尸唐诗躺尸，偶尔加班加班加班，或者跟着几个朋友在家消遣时间打打麻将，扑克牌玩一下！

尤其是放长假【ps:也没啥假，长假就是过年】在老家的时候，亲戚尤其多，七大姑八大姨的一年好不容易聚一次，打打麻将跟扑克这是常有的事儿，联络下感情这是最快的方式~

说起打扑克，我们经常就是玩儿的二百四、炸金花、三个打一个那就是叫啥名字来着，容我想想......

话说真词穷，我们那都是方言撒，我翻译不过来普通话是叫什么了，我估计240你们也没听懂是啥，23333~

今天的话小编是带大家做一款21点的扑克游戏！

有大佬可优化一下这个代码，做一个精致豪华的界面就好了~~

正文

游戏规则：21点又名黑杰克，该游戏由2到6个人玩，使用除大小王之外的52张牌，游戏者的目标是使手中的牌的点数之和不超过21点且尽量大。当使用1副牌时，以下每种牌各一张（没有大小王）：

（1）初始化玩家数：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def iniGame():
    global playerCount, cards
    while(True):
        try:
            playerCount = int(input('输入玩家数：'))
        except ValueError:
            print('无效输入！')
            continue
        if playerCount < 2:
            print('玩家必须大于1！')
            continue
        else:
            break
    try:
        decks = int(input('输入牌副数：（默认等于玩家数）'))
    except ValueError:
        print('已使用默认值！')
        decks = playerCount
    print('玩家数：', playerCount, '，牌副数：', decks)
    cards = getCards(decks)  # 洗牌</span></span></span>

（2）建立了玩家列表，电脑跟玩家对战。

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def createPlayerList():
    global playerList
    playerList = []
    for i in range(playerCount):
        playerList += [{'id': '', 'cards': [], 'score': 0}].copy()
        playerList[i]['id'] = '电脑' + str(i+1)
    playerList[playerCount-1]['id'] = '玩家'
    random.shuffle(playerList)  # 为各玩家随机排序</span></span></span>

（3）开始会设置2张明牌玩法都可以看到点数。

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def gameStart():
    print('为各玩家分2张明牌：')
    for i in range(playerCount):  # 为每个玩家分2张明牌
        deal(playerList[i]['cards'], cards, 2)
        playerList[i]['score'] = getScore(playerList[i]['cards'])  # 计算初始得分
        print(playerList[i]['id'], ' ', getCardName(playerList[i]['cards']),
              ' 得分 ', playerList[i]['score'])
        )</span></span></span>

（4）游戏为电脑跟玩家依次分发第三张暗牌，这是别人看不到的。

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def gamePlay():
    for i in range(playerCount):
        print('当前', playerList[i]['id'])
        if playerList[i]['id'] == '玩家':  # 玩家
            while(True):
                print('当前手牌：', getCardName(playerList[i]['cards']))
                _isDeal = input('是否要牌？（y/n）')
                if _isDeal == 'y':
                    deal(playerList[i]['cards'], cards)
                    print('新牌：', getCardName(playerList[i]['cards'][-1]))
                    # 重新计算得分:
                    playerList[i]['score'] = getScore(playerList[i]['cards'])
                elif _isDeal == 'n':
                    break
                else:
                    print('请重新输入！')
        else:  # 电脑
            while(True):
                if isDeal(playerList[i]['score']) == 1:  # 为电脑玩家判断是否要牌
                    deal(playerList[i]['cards'], cards)
                    print('要牌。')
                    # 重新计算得分:
                    playerList[i]['score'] = getScore(playerList[i]['cards'])
                else:
                    print('不要了。')
                    break
        )</span></span></span>

（5）随机洗牌：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def getCards(decksNum):
    cardsList = ['Aa', 'Ab', 'Ac', 'Ad',
                 'Ka', 'Kb', 'Kc', 'Kd',
                 'Qa', 'Qb', 'Qc', 'Qd',
                 'Ja', 'Jb', 'Jc', 'Jd',
                 '0a', '0b', '0c', '0d',
                 '9a', '9b', '9c', '9d',
                 '8a', '8b', '8c', '8d',
                 '7a', '7b', '7c', '7d',
                 '6a', '6b', '6c', '6d',
                 '5a', '5b', '5c', '5d',
                 '4a', '4b', '4c', '4d',
                 '3a', '3b', '3c', '3d',
                 '2a', '2b', '2c', '2d']
    cardsList *= decksNum       # 牌副数
    random.shuffle(cardsList)   # 随机洗牌
    return cardsList</span></span></span>

（6）设置牌名字典：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">cardNameDict = {'Aa': '黑桃A', 'Ab': '红桃A', 'Ac': '梅花A', 'Ad': '方片A',
                'Ka': '黑桃K', 'Kb': '红桃K', 'Kc': '梅花K', 'Kd': '方片K',
                'Qa': '黑桃Q', 'Qb': '红桃Q', 'Qc': '梅花Q', 'Qd': '方片Q',
                'Ja': '黑桃J', 'Jb': '红桃J', 'Jc': '梅花J', 'Jd': '方片J',
                '0a': '黑桃10', '0b': '红桃10', '0c': '梅花10', '0d': '方片10',
                '9a': '黑桃9', '9b': '红桃9', '9c': '梅花9', '9d': '方片9',
                '8a': '黑桃8', '8b': '红桃8', '8c': '梅花8', '8d': '方片8',
                '7a': '黑桃7', '7b': '红桃7', '7c': '梅花7', '7d': '方片7',
                '6a': '黑桃6', '6b': '红桃6', '6c': '梅花6', '6d': '方片6',
                '5a': '黑桃5', '5b': '红桃5', '5c': '梅花5', '5d': '方片5',
                '4a': '黑桃4', '4b': '红桃4', '4c': '梅花4', '4d': '方片4',
                '3a': '黑桃3', '3b': '红桃3', '3c': '梅花3', '3d': '方片3',
                '2a': '黑桃2', '2b': '红桃2', '2c': '梅花2', '2d': '方片2'}</span></span></span>

（7）判断胜负：

<span style="color:#333333"><span style="background-color:#ffffff"><span style="background-color:#f8f8f8">def showWinAndLose():
    loserList = []  # [['id', score], ['id', score], ...]
    winnerList = []  # [['id', score], ['id', score], ...]
    winnerCount = 0
    loserCount = 0
    for i in range(playerCount):
        if playerList[i]['score'] > 21:  # 爆牌直接进入败者列表
            lo([playerList[i]['id'],  playerList[i]['score']])
        else:  # 临时胜者列表
            winnerLi([playerList[i]['id'], playerList[i]['score']])
    if len(winnerList) == 0:  # 极端情况：全部爆牌
        print('全部玩家爆牌：')
        for i in range(len(loserList)):
            print(loserList[i][0], loserList[i][1])
    elif len(loserList) == 0:  # 特殊情况：无人爆牌
        winnerLi(key=lambda x: x[1], reverse=True)  # 根据分数值排序胜者列表
        for i in range(len(winnerList)):  # 计算最低分玩家数量
            if i != len(winnerList)-1:
                if winnerList[-i-1][1] == winnerList[-i-2][1]:
                    loserCount = (i+2)
                else:
                    if loserCount == 0:
                        loserCount = 1
                    break
            else:
                loserCount = len(loserList)
        if loserCount == 1:
            lo())
        else:
            while(len(loserList) != loserCount):
                lo())
        for i in range(len(winnerList)):  # 计算最高分玩家数量
            if i != len(winnerList)-1:
                if winnerList[i][1] == winnerList[i+1][1]:
                    winnerCount = (i+2)
                else:
                    if winnerCount == 0:
                        winnerCount = 1
                    break
            else:
                winnerCount = len(winnerList)
        while(len(winnerList) != winnerCount):
            winnerLi()
        print('获胜：')
        for i in range(len(winnerList)):
            print(winnerList[i][0], winnerList[i][1])
        print('失败：')
        for i in range(len(loserList)):
            print(loserList[i][0], loserList[i][1])
    else:  # 一般情况：有人爆牌
        winnerLi(key=lambda x: x[1], reverse=True)  # 根据分数值排序胜者列表
        for i in range(len(winnerList)):  # 计算最高分玩家数量
            if i != len(winnerList)-1:
                if winnerList[i][1] == winnerList[i+1][1]:
                    winnerCount = (i+2)
                else:
                    if winnerCount == 0:
                        winnerCount = 1
                    break
            else:
                winnerCount = len(winnerList)
        while(len(winnerList) != winnerCount):
            winnerLi()
        print('获胜：')
        for i in range(len(winnerList)):
            print(winnerList[i][0], winnerList[i][1])
        print('失败：')
        for i in range(len(loserList)):
            print(loserList[i][0], loserList[i][1])</span></span></span>

游戏效果：咳咳咳.......感觉这游戏看运气也看胆量！！
