你好。 我正在嘗試制作紙牌游戲，但是我不確定如何使所有紙牌都獨一無二，就像在紙牌中一樣。 換句話說，我不希望有任何重復的內容。 我遇到的另一個問題是，當我嘗試將信息添加到詞典rem時，不會打印具有相同值的所有卡片。 謝謝。

Answer 1

就個人而言，這就是我要做的：

card_type = ["Ace", "2", "3", "4", "5", "6", "7", "8", "9", "10", "Joker", "Queen", "King"]
card_vals = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13]
card_suit = ["Spade", "Clubs", "Diamond", "Hearts"]
internal_deck = []
display_deck = []
for i in range(0, len(card_type), 1):
    for j in range(0, len(card_suit), 1):
        internal_deck.append((card_type[i], card_suit[j], card_vals[i]))
        display_deck.append(card_type[i] + " of " + card_suit[j])
for cards in display_deck:
    print(cards)

如果您想知道為什么有兩個列表，這就是為什么。 我希望一種功能更多，可以將卡打印到屏幕上，另一種功能則可以更好地處理用戶看不到的內部事物。

Answer 2

您應該將已挑選的卡片存儲在列表中，而不是字典中。 這樣，它可以跟蹤具有相同價值或相同花色的多張牌。

適應您當前代碼的最簡單方法是添加一個while循環，該循環使揀選卡尚未存儲在hand （已揀選的卡列表）。

# ...
hand = []
for _ in range(NUM_CARDS):
    while True:
        cv = random.randint(2,14)#value
        cs = random.randint(0,3)#suit
        if (cv, cs) not in hand:
            break
    hand.append((cv, cs))
    cards[0].append('_' * (CARD_WIDTH+2))
    cards[1].append(card_row(''))
    cards[2].append(card_row(get_card_name(cv)))
    cards[3].append(card_row('of'))
    cards[4].append(card_row(SUITS[cs][0]))
    cards[5].append(card_row(SUITS[cs][1]*(CARD_WIDTH)))
    cards[6].append(card_row("_" * CARD_WIDTH))
print 'Welcome to SANDCRAB. This is your deck of cards.'
for card in hand:
    print card
for lst in cards:
    print ''.join(lst)

或者，將卡片存儲在集合中而不是列表中：

hand = set()
while len(hand) < NUM_CARDS:
    hand.add((random.randint(2,14), random.randint(0, 3))

您還可以簡化輸出，例如：

def card_output(value, suit_number):
    suit, symbol = SUITS[suit_number]
    return ['_' * (CARD_WIDTH + 2)] + map(card_row, [
        '', 
        NAMES.get(value, "%2d" % value),
        'of',
        suit,
        symbol * CARD_WIDTH, 
        '_' * CARD_WIDTH])

# method 1. randomly select until we have 5 unique values
hand1 = set()
while len(hand1) < NUM_CARDS:
    hand1.add((random.randint(2, 14), random.randint(0, 3)))

# method 2. make a deck then sample 5 cards from it
deck = [(value, suit_number) for value in range(2, 14) for suit_number in range(3)]
hand2 = random.sample(deck, NUM_CARDS)

print 'Welcome to SANDCRAB. This is your deck of cards.'
for hand in [hand1, hand2]:
    for row in zip(*[card_output(value, suit_number) for value, suit_number in hand]):
        print ''.join(row)
