python3中的列表值（ValueError）有问题

Question

我正在尝试为学校创建一个简单的纸牌游戏，我正在编写游戏如何在游戏中运行的代码，并且在尝试从列表中删除值时遇到一个ValueError

我已经尝试过更改list.remove(x)语法，到目前为止我已经尝试过list.remove(list[x])、list.remove([x])和list.remove(x)，但是所有这些都返回了ValueError。你知道吗

import random, time #imports required modules for the code

cardDeck = []
player1 = []
player1CardsWon = []
player2 = []
player2CardsWon = [] #all these lists/arrays are needed later on in the code

def deckCreator(): #creates all the needed embedded lists inside the cardDeck 2D Array
  for color in ["yellow", "red", "black"]:
    for number in [1,2,3,4,5,6,7,8,9,10]:
      cardDeck.append([color, number])

'''test 1 - to check if deckCreator function is working
deckCreator()
print(cardDeck)
'''

def deckShuffle(): #shuffles the cardDeck 2D Array
  random.shuffle(cardDeck)

'''test 2 - to check if the deckShuffle function is working
deckCreator()
print(cardDeck)

我希望控制台输出：

Player 2 holds card black 8 for this round
Player 1 wins!

但它目前正在输出：

Player 1 holds card red 9 for this round
Player 2 holds card black 8 for this round

ValueError: list.remove(x): x not in list

Answer 1

list.remove(x)

从列表中删除值为x的元素（使用相等匹配查找要删除的内容）

每当列表中不存在要删除的对象时，list.remove抛出ValueError。你知道吗

您正在创建一个列表列表。每个元素都是[color, number]。因此，一旦你从甲板弹出你有一个类似[color, number]的元素。但是您试图删除0（这不是一个列表），因此您会得到错误。我不知道你为什么要打电话给remove。无论如何，这些变量将在下一个循环中重新分配。你也没有使用修改过的变量。所以试着去掉那些线。你知道吗

Answer 2

你的问题是你使用remove的方式。您正在使用索引作为remove的参数，同时需要传递元素本身。你知道吗

示例：

lst = [1,'yellow']
# If you want to remove yellow call
lst.remove('yellow')
# and not
lst.remove(1)
# If you want to remove 1 call
lst.remove(1)
# and not
lst.remove(0)
