python - 如何限制生成特定随机数的次数python

我目前正在作为一个类项目在python中开发一个内存游戏。我正在尝试生成0到3之间的随机数，这将对应于某张卡。问题是，我只需要每张卡片出现两次。不多也不少。
这是我当前的代码：

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

最佳答案

当你有一组特定的项目在你周围游荡时，做独立的随机选择不是一个好方法。请改为：

import random
cards = ["___TI___", "___GK___", "___QW___", "___KJ___"]
boardTemp1 = cards * 2
random.shuffle(boardTemp1)
print(boardTemp1)
