导语
昨天不是周天嘛？
你们在家放松一般都会做什么呢？
周末逛逛街，出去走走看电影......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~~

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"])
time.sleep(1.5)</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
time.sleep(1.5)</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
loserList.append([playerList[i]["id"], playerList[i]["score"]])
else: # 临时胜者列表
winnerList.append([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
winnerList.sort(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:
loserList.append(winnerList.pop())
else:
while(len(loserList) != loserCount):
loserList.append(winnerList.pop())
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):
winnerList.pop()
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
winnerList.sort(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):
winnerList.pop()
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！！
