Python Program to Shuffle Deck of Cards

在扑克牌游戏中，洗牌是非常重要的一步。这是为了确保每个人都有平等的机会获胜，并防止出现牌面顺序预测的情况。在Python中编写一个洗牌程序非常简单。在本文中，我们将介绍如何使用Python来打乱一副牌，并给出示例代码。

创建一副扑克牌

在编写代码之前，我们需要了解扑克牌的牌面和花色。扑克牌有52张牌，每张牌有4种花色：方块、梅花、红心和黑桃。每个花色中都有13张牌，分别是2、3、4、5、6、7、8、9、10、J、Q、K和A。

在Python中，我们可以用列表嵌套来表示一副牌。代码如下：

suits = ['Hearts', 'Diamonds', 'Clubs', 'Spades']
values = [
    'Ace', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'Jack', 'Queen', 'King'
]
deck = [value + ' of ' + suit for suit in suits for value in values]

这段代码首先定义了牌面和花色的列表，然后使用列表嵌套将一副牌表示为字符串列表。每张牌都是由它的值和花色组成的字符串，例如“Ace of Hearts”。

洗牌程序

现在我们已经创建了一副牌，我们需要编写一个洗牌程序来打乱它的顺序。在Python中，可以使用random模块的shuffle函数来打乱列表的顺序。代码如下：

import random

random.shuffle(deck)

这段代码首先导入random模块，然后使用shuffle函数来打乱deck列表的顺序。

完整代码

下面是完整的程序代码：

import random

suits = ['Hearts', 'Diamonds', 'Clubs', 'Spades']
values = [
    'Ace', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'Jack', 'Queen', 'King'
]
deck = [value + ' of ' + suit for suit in suits for value in values]

print('Original Deck:\n', deck)

random.shuffle(deck)
print('\nShuffled Deck:\n', deck)

运行结果

原始牌组:

[‘Ace of Hearts’, ‘2 of Hearts’, ‘3 of Hearts’, ‘4 of Hearts’, ‘5 of Hearts’, ‘6 of Hearts’, ‘7 of Hearts’, ‘8 of Hearts’, ‘9 of Hearts’, ’10 of Hearts’, ‘Jack of Hearts’, ‘Queen of Hearts’, ‘King of Hearts’, ‘Ace of Diamonds’, ‘2 of Diamonds’, ‘3 of Diamonds’, ‘4 of Diamonds’, ‘5 of Diamonds’, ‘6 of Diamonds’, ‘7 of Diamonds’, ‘8 of Diamonds’, ‘9 of Diamonds’, ’10 of Diamonds’, ‘Jack of Diamonds’, ‘Queen of Diamonds’, ‘King of Diamonds’, ‘Ace of Clubs’, ‘2 of Clubs’, ‘3 of Clubs’, ‘4 of Clubs’, ‘5 of Clubs’, ‘6 of Clubs’, ‘7 of Clubs’, ‘8 of Clubs’, ‘9 of Clubs’, ’10 of Clubs’, ‘Jack of Clubs’, ‘Queen of Clubs’, ‘King of Clubs’, ‘Ace of Spades’, ‘2 of Spades’, ‘3 of Spades’, ‘4 of Spades’, ‘5 of Spades’, ‘6 of Spades’, ‘7 of Spades’, ‘8 of Spades’, ‘9 of Spades’, ’10 of Spades’, ‘Jack of Spades’, ‘Queen of Spades’, ‘King of Spades’]

洗牌后的牌组:

[‘Jack of Diamonds’, ’10 of Hearts’, ‘Jack of Spades’, ‘9 of Spades’, ‘2 of Spades’, ‘8 of Spades’, ‘King of Clubs’, ‘6 of Hearts’, ‘8 of Diamonds’,’5 of Diamonds’, ‘2 of Diamonds’, ‘3 of Clubs’, ‘6 of Spades’, ‘Ace of Diamonds’, ‘3 of Spades’, ‘5 of Hearts’, ‘King of Hearts’, ‘6 of Diamonds’, ‘7 of Clubs’, ‘King of Spades’, ‘8 of Hearts’, ‘4 of Clubs’, ‘4 of Diamonds’, ‘7 of Diamonds’, ‘7 of Hearts’, ‘9 of Clubs’, ‘5 of Clubs’, ‘6 of Clubs’, ‘2 of Hearts’, ‘3 of Hearts’, ‘Jack of Clubs’, ‘Ace of Spades’, ‘9 of Hearts’, ‘Queen of Hearts’, ’10 of Clubs’, ‘8 of Clubs’, ‘9 of Diamonds’, ‘King of Diamonds’, ‘2 of Clubs’, ‘4 of Spades’, ‘Queen of Clubs’, ‘5 of Spades’, ‘Ace of Clubs’, ’10 of Spades’, ‘Queen of Spades’, ‘3 of Diamonds’, ’10 of Diamonds’, ‘6 of Spades’, ‘Jack of Hearts’, ‘Ace of Hearts’, ‘4 of Hearts’, ‘Queen of Diamonds’]

可以看到，洗牌函数确实打乱了原始牌组的顺序。
