二十一点游戏转换问题编辑

Question

我想在每次新一轮之前制作一个二十一点游戏，程序检查以确保每个玩家有7张牌。如果没有，甲板会清除，重新填充和重新洗牌。我遇到的大部分问题都没有解决，但由于某种原因，在每笔交易开始时，它不止一次地重新洗牌，我无法弄清楚原因。请帮助。 这是我到目前为止有： （PS进口卡和游戏模块不是问题的一部分，我确信我的问题在于我BJ_Deck类的交易（）函数。）

由于有人决定称之为“心理调试”，我会继续告诉你模块是什么。 这里的卡模块：

class Card(object): 
""" A playing card. """ 
RANKS = ["A", "2", "3", "4", "5", "6", "7", 
     "8", "9", "10", "J", "Q", "K"] 
SUITS = ["c", "d", "h", "s"] 

def __init__(self, rank, suit, face_up = True): 
    self.rank = rank 
    self.suit = suit 
    self.is_face_up = face_up 

def __str__(self): 
    if self.is_face_up: 
     rep = self.rank + self.suit 
    else: 
     rep = "XX" 
    return rep 

def flip(self): 
    self.is_face_up = not self.is_face_up 

类手（对象）： “” “的扑克牌一只手 ”“” DEF 初始化（个体）： self.cards = []

def __str__(self): 
    if self.cards: 
     rep = "" 
     for card in self.cards: 
      rep += str(card) + "\t" 
    else: 
     rep = "<empty>" 
    return rep 

def clear(self): 
    self.cards = [] 

def add(self, card): 
    self.cards.append(card) 

def give(self, card, other_hand): 
    self.cards.remove(card) 
    other_hand.add(card) 

类甲板（手）： “” “的一副扑克牌。 ”“” 高清填充（个体经营）：用于西装 在Card.SUITS：对于排名在Card.RANKS ： self.add（卡（等级，花色））

def shuffle(self): 
    import random 
    random.shuffle(self.cards) 

def deal(self, hands, per_hand = 1): 
    for rounds in range(per_hand): 
     for hand in hands: 
      if self.cards: 
       top_card = self.cards[0] 
       self.give(top_card, hand) 
      else: 
       print "Can't continue deal. Out of cards!" 

如果名 == “主要”： 打印 “这是班打牌的模块。” 的raw_input（ “\ n \ n按回车键退出”）

而这里的游戏模块：

class Player(object): 
""" A player for a game. """ 
def __init__(self, name, score = 0): 
    self.name = name 
    self.score = score 

def __str__(self): 
    rep = self.name + ":\t" + str(self.score) 
    return rep 

高清ask_yes_no（问题）： “”“问一个yes或no的问题。 “”” 响应=无 而响应不是（ “Y”， “N”）： 响应的raw_input =（问题）.lower（） 返回响应

DEF ask_number（问题，低，高）： “”“在跑步中询问一个号码GE “” “ 响应=无 而响应不在范围内（低，高）： 响应= INT（的raw_input（问题）） 返回响应

如果名称 ==”。主“： print“你直接运行这个模块（并没有'导入'）。” raw_input（“\ n \ n按回车键退出。”）

Answer 1

Nosklo指出了一个问题（在循环中检查它），但还有第二个问题。

if len(self.cards)>=7*(len(hands)): 

被检查是否卡的数量大于所需要的数目，并且如果这样的条件下，将清除甲板，填充和混洗。

当与循环内部的检查相结合时，它会在每次开始新一轮时重新填充和洗牌甲板。

所以你可能会是这样的：

if len(self.cards) <= 7*(len(hands)): 
      print "Reshuffling the deck." 
      self.cards=[] 
      self.populate() 
      self.shuffle() 
    for rounds in range(per_hand): 
     for hand in hands: 
       top_card=self.cards[0] 
       self.give(top_card, hand) 

Answer 2

你一遍又一遍地检查它，在循环中，当你分发卡片时，卡组正在缩小，我想（可以在您的代码中看不到Deck.give方法以确定）。

您可能只想检查一次，将检查移到循环之外。

def deal(self, hands, per_hand=1): 
    for rounds in range(per_hand): 
     if len(self.cards) <= 7 * len(hands): 
      print "Reshuffling the deck." 
      self.cards = [] 
      self.populate() 
      self.shuffle() 
     for hand in hands: 
      top_card=self.cards[0] 
      self.give(top_card, hand) 

Answer 3

for hand in hands:

你真的要运行每手是什么逻辑？
