如何将变量与集合进行比较(以查看是否存在重复的变量)，如果存在，如何删除它们并重复该过程？

Question

我是新来的，所以我很抱歉这不是问问题的好方法.

这是我的密码：

import random
i = 0
#the numbers of the cards
numbers = ["A","2","3","4","5","6","7","8","9","10","Jack","Queen","King"]
#the suits of decks
suits = ["Spades","Hearts","Clubs","Diamonds"]
#empty list
used = []
#Generate random Number and Suit
while i != 5:
    number = random.choice(numbers)
    suit = random.choice(suits)
    print (number+" of "+suit)
    used.append(number + " of " + suit)
    i += 1

我试图实现的是让代码生成一系列的5张卡片(没有副本)，然后打印那些.

但我不知道如何处理(和重复代码)重复的

我现在得到的是：

黑桃王，黑桃王，红桃皇后，红桃之王，黑桃王，红桃皇后，棒子A，红桃6

提前感谢！

Answer 1

试试这个：

import itertools
import random
numbers = ["A","2","3","4","5","6","7","8","9","10","Jack","Queen","King"]
#the suits of decks 
suits = ["Spades","Hearts","Clubs","Diamonds"]
deck=list(itertools.product(numbers,suits))
random.shuffle(deck)
for i in range(5):
    print( deck[i][0],'of' ,deck[i][1])

Answer 2

若要摆脱复制卡，请尝试按以下方式添加行：

# Generate random Number and Suit
while i != 5:
    number = random.choice(numbers)
    numbers.remove(number) ###
    suit = random.choice(suits)
    print(number + " of " + suit)
    used.append(number + " of " + suit)
    i += 1
