简单的Python卡牌游戏

Question

我对 python 完全陌生，我不知道如何处理这个程序。

我正在尝试构建一个迷你纸牌游戏，它可以执行以下操作

1. 有六名玩家。
2. 每手牌开始时，每位玩家都会收到四张牌。
3. 对于每个玩家，他们手上的所有对子都会被放下。对于由两张点数小于 10 的牌组成的对子（其中 A 的点数大于 10），玩家可获得 1 分。对于由两张 10 级或以上的牌组成的付款者，玩家可获得 2 分。如果手牌为两对，则均放下。玩家根据该对的类型获得相应的分数（1 或 2）。
4. 牌局在对子掉落后结束。 （玩家实际上并没有输入信息或做出决定。我告诉过你这是一个无聊的游戏。）所有牌都返回到牌堆中，重新洗牌，并开始新的一手牌。
5. 每轮结束后，选手按照总积分降序排列。如果两名玩家得分相同，则首先打印得分最低的玩家。
6. 六轮过后，比赛结束。得分列表中的第一个玩家（如上所定义）赢得了游戏

输出应该如下所示：

Hand 1 deal:
Player 1's hand: 5D 5H KD AS
Player 2's hand: 7D 8D 9C JS
Player 3's hand: 3D 3H 6S 7C
Player 4's hand: 4C 6D 8S TH
Player 5's hand: 4H 5C 7S QC
Player 6's hand: 5S 6H 9H KH

Dropping pairs:
Player 1 dropped 1 pair.
Player 2 dropped no pairs.
Player 3 dropped 1 pair.
Player 4 dropped no pairs.
Player 5 dropped no pairs.
Player 6 dropped no pairs.

Score:
Player 1: 1
Player 3: 1
Player 2: 0
Player 4: 0
Player 5: 0
Player 6: 0

我为该游戏提供的模块包括。

i was really hoping if someone could help me with the loops that this program needs, especially the point loop system. 
this what i have so far,

import random

new = cards.small_deck()

print cards.hand_string(new)
print len(new)


player1 = []
player2 = []
player3 = []
player4 = []
player5 = []
player6 = []
#shuffle the cards
random.shuffle(new)
num = input('How many cards to deal to each player? ')
while num > 0:
        player1.append(new.pop(0))
        player2.append(new.pop(0))
        player3.append(new.pop(0))
        player4.append(new.pop(0))
        player5.append(new.pop(0))
        player6.append(new.pop(0))
        num = num - 1
#prints out 8 cards for each person

print 'the cards remaining in the deck are: '
print len(new)

#sorts player1 cards and removes the pairs
player1.sort()
print "sorted hand for player 1:"
print cards.hand_string(player1)
newplayer1 = []
player1points = 0

newplayer1, player1points = cards.drop_pair(player1)
print cards.hand_string(newplayer1)

#sorts player2 cards
player2.sort()
print "sorted hand for player 2:"
print cards.hand_string(player2)
newplayer2 = []
player2points = 0

newplayer2, player1points = cards.drop_pair(player2)
print cards.hand_string(newplayer2)



#sorts player3 cards
player3.sort()
print "sorted hand for player 3:"
print cards.hand_string(player3)
newplayer3 = []
player3points = 0

newplayer3, player1points = cards.drop_pair(player3)
print cards.hand_string(newplayer3)   


#sorts player4 cards
player4.sort()
print "sorted hand for player 4:"
print cards.hand_string(player4)
newplayer4 = []
player4points = 0

newplayer4, player1points = cards.drop_pair(player4)
print cards.hand_string(newplayer4)


#sorts player5 cards
player5.sort()
print "sorted hand for player 5:"
print cards.hand_string(player5)

在循环方面遇到了很大的麻烦，非常感谢我能得到的任何帮助，提前谢谢你

Answer 1

您似乎根本不使用 pointsort.py，这很好，因为我最终不需要它来实现您的预​​期输出。

# main.py
import cards
import random

deck = cards.small_deck()

class Player(object):
    def __init__(self, number):
        self.number = number
        self.points = 0
        self.hand = []

    def __str__(self):
        return "Player %d" % self.number

players = [Player(num + 1) for num in xrange(6)]  # create six numbered players
rounds = 6
hand_size = 4

for round_num in xrange(rounds):
    #shuffle the cards
    random.shuffle(deck)
    print "Hand %d deal:" % (round_num + 1)
    # deal cards
    for _ in xrange(hand_size):
        for player in players:
            # draw from the back instead of the front: possibly slightly more efficient
            player.hand.append(deck.pop())

    # sort player cards
    for player in players:
        player.hand.sort()
        print "%s's hand: %s" % (player, cards.hand_string(player.hand))
    print

    print "Dropping pairs:"
    for player in players:
        #removes the pairs
        new_hand, dropped_cards, pairs = cards.drop_pairs(player.hand)
        deck.extend(player.hand)  # realistically we can dump the hand now anyway.
        player.hand = []

        player.points += pairs

        how_many = pairs
        plural = "s"
        if pairs == 0:
            how_many = "no"
        elif pairs == 1:
            plural = ""
        print "%s dropped %s pair%s" % (player, how_many, plural)
    print

    print "Score:"
    for player in players:
        print "%s: %d" % (player, player.points)
    print

我还将 drop_pair 更改为 drop_pairs，并使其找到所有对，而不仅仅是一对。如果找到 3 个同类值 2 分，4 个同类值 3 分。

# in cards.py
def drop_pairs(hand):
    new_hand = hand[:]
    dropped_cards = []
    pairs = 0
    for card1, card2 in zip(hand, hand[1:]):  # look at every two-in-a-row cards
        if card1.rank() == card2.rank():
            try:
                new_hand.remove(card1)
            except ValueError:
                pass
            else:
                dropped_cards.append(card1)
            try:
                new_hand.remove(card2)
            except ValueError:
                pass
            else:
                dropped_cards.append(card2)
            pairs += 1
    return new_hand, dropped_cards, pairs

我没有查看您的所有代码，也没有比“循环帮助”更具体的指导，我虽然帮不了什么忙，但我注意到了一些事情：

• 在 python 中，你可以直接迭代列表，而不是从 0 迭代到 len - 1 并检查索引。例如：

  # 这可以工作，但不推荐
  对于范围内的套装(len(suits))：
      对于范围内的排名（len（ranks））：
          c = 卡(等级[等级], 套装[套装])
          d.追加(c)
  
  # 这更干净
  对于西装中的西装：
      对于排名：
          d.append(卡牌(等级、花色))
  

• 但是，有时您确实想要迭代一系列连续数字，或者您只是希望某些代码运行一定次数，在这种情况下您可以使用 range （或 xrange，在 python 2 中对于大范围更有效）

  # 不要这样做
  当 num > 时0:
      做某事（）
      数字 = 数字 - 1
  
  # 改为这样做！
  对于 xrange(num) 中的 i：
      做某事（）
  

此外，如果您不需要当前数字的“i”变量，则可以使用名称“_”，它经常被重新分配，并且是垃圾数据的好地方。

• 您还可以嵌套列表。如果您不确定将拥有多少个列表，这非常有用。也就是说，如果你有六名玩家：

  <前><代码># 不不不
  玩家1 = []
  玩家2 = []
  玩家3 = []
  玩家4 = []
  玩家5 = []
  玩家6 = []

  ＃ 更好的...
  玩家 = [[], [], [], [], [], []]

  ＃ 是的！
  玩家=[]
  对于 xrange(6) 中的 _：
  玩家.append([])

  # 还有一个名为“列表推导式”的快捷方式，它允许我们
  # 让我们的列表定义更加简洁。
  玩家 = [[] for _ in xrange(6)]

后两个例子的优点是你可以通过改变数字6，甚至使用变量来轻松改变游戏中有多少个玩家。他们还减少了代码重复：每个玩家处理牌的逻辑被复制粘贴 6 次，而他们之间只改变了一个数字。这不太可扩展：如果您想添加或删除玩家，则必须在代码中添加或删除许多重复的块。反而：

    # no! bad!
    player1 = []
    player2 = []
    player3 = []
    player4 = []
    player5 = []
    player6 = []

    player1.do_stuff()
    player2.do_stuff()
    player3.do_stuff()
    player4.do_stuff()
    player5.do_stuff()
    player6.do_stuff()

    # much easier!
    for player in players:
        player.do_stuff()
