我如何使用函數將兩個 arrays 洗牌，以便打印出隨機卡

Question

我希望它通過洗牌來打印一張隨機卡片，例如 4 of heart 這是我當前的代碼，它一直打印 None of None

提前致謝

def exchange(SUITS, i, suits):
    temp = SUITS[i]
    SUITS[i] = SUITS[suits]
    SUITS[suits] = temp
    return SUITS[suits]

def shuffle():
    SUITS = ['Clubs', 'Diamonds', 'Hearts' , 'Spades']
    n = len(SUITS)
    for i in range(n):
        suits = random.randrange(0,n)
        exchange(SUITS,i, suits)

def exchange2(RANKS, i, ranks):
    Temp = RANKS[i]
    RANKS[i] = RANKS[ranks]
    RANKS[ranks] = Temp
    return RANKS[ranks]

def shuffle2():
    RANKS = ['2', ' 3', '4', '5', '6' , '7' , '8', '9','10',
        'Jack', 'Queen', 'King','Ace']
    n = len(RANKS)
    for i in range(n):
        ranks = random.randrange(0,n)
        exchange2(RANKS,i, ranks)
        
w = shuffle()
z = shuffle2()


print(str(z) + ' of ' + str(w))

Answer 1

python 隨機庫有一個shuffle() function 用於列出您的 function 沒有返回任何內容，因此您的打印語句將為空。

Answer 2

根據我在您的問題陳述中的理解，我想您可以簡單地執行以下操作：

import random

def shuffle():
    SUITS = ['Clubs', 'Diamonds', 'Hearts' , 'Spades']
    RANKS = ['2', ' 3', '4', '5', '6' , '7' , '8', '9','10',
        'Jack', 'Queen', 'King','Ace']
    randomSuit = random.randrange(0, len(SUITS))
    randomRank = random.randrange(0, len(RANKS))
    print(RANKS[randomRank] + " of " + SUITS[randomSuit])
    
    
shuffle()

讓我知道這是否是您所期望的。

如果你想從不同的函數中得到等級和花色，那么也可以稍微修改一下來實現。

import random

def shuffleRank():
    RANKS = ['2', ' 3', '4', '5', '6' , '7' , '8', '9','10',
        'Jack', 'Queen', 'King','Ace']
    randomRank = random.randrange(0, len(RANKS))
    return RANKS[randomRank] 
    
def shuffleSuit():
    SUITS = ['Clubs', 'Diamonds', 'Hearts' , 'Spades']
    randomSuit = random.randrange(0, len(SUITS))
    return SUITS[randomSuit]


print (shuffleRank() + " of " + shuffleSuit())
