如何限制Python生成特定随机数的次数

Question

我目前正在用python作为一个类项目开发一个内存游戏。我尝试生成0到3之间的随机数，这将对应于某张卡。问题是，我需要每张牌只出现两次。不多也不少。在

以下是我当前的代码：

import random
cards = ["___TI___", "___GK___", "___QW___", "___KJ___"]
boardTemp1 = ['1', '2',
              '3', '4',
              '5', '6',
              '7', '8']

def shuffle():

    cardChoose = random.randint(0, 3)
    boardChoose = random.randint(0, 7)
    randCard = 9
    randCard = cards[cardChoose]
    boardTemp1[boardChoose] = cards[cardChoose]
    return randCard

boardTemp1[0] = shuffle()
boardTemp1[1] = shuffle()
boardTemp1[2] = shuffle()
boardTemp1[3] = shuffle()
boardTemp1[4] = shuffle()
boardTemp1[5] = shuffle()
boardTemp1[6] = shuffle()
boardTemp1[7] = shuffle()


print(boardTemp1)

谢谢你的帮助

Answer 1

我会列出每一张牌两次，然后随机化列表而不是棋盘，然后将每张牌从列表中移除，同时将其放在棋盘上：

import random

cards = [1, 1, 2, 2, 3, 3, 4, 4]
random.shuffle(cards)

while cards:
    card = cards.pop()
    # place each card on the board sequentially
