当我运行以下代码时，我收到以下错误消息：
IndexError：列出超出范围的索引
是什么原因导致的？
cardChosen = deck[random.randint(0, len(deck))]
应该在每一轮都保持最大射程的下降，但程序说我超出了射程。
import random
deck = [2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14] * 4
scorePlayer1 = 0
scorePlayer2 = 0
player1 = input("Player 1: ")
player2 = input("Player 2: ")
while len(deck) > 0:
def player_turn(player_name, deck):
deck = deck
print(len(deck))
cardChosen = deck[random.randint(0, len(deck))]
deck.remove(cardChosen)
print(player_name + " chose " + str(cardChosen))
return(cardChosen)
a = player_turn(player1, deck)
b = player_turn(player2, deck)
if a > b:
scorePlayer1 += 2
print(player1 + " wins this round:)")
elif b > a:
scorePlayer2 += 2
print(player2 + " wins this round :)")
elif a == b:
print("War!")
print(scorePlayer1)
print(scorePlayer2)
else:
print("Game Over")
if scorePlayer1 > scorePlayer2:
print(player1 + " has won the game:)")
elif scorePlayer2 > scorePlayer1:
print(player2 + " has won the game:)")
elif scorePlayer1 == scorePlayer2:
print("There has been a tie, both players won:)")
您获取的随机项目1太远。
当列表的长度为1并且您只剩下一个选择时，cardChosen = deck[random.randint(0, len(deck))]相当于不存在的cardChosen = deck[0]或deck[1]。
您要使用random.randint(0, len(deck)-1)。
编辑：始终检查您使用的库的文档。例如，内置的range(a, b)不包括b，而random.randint(a, b)包括。
我鼓励您看看代码的这种格式。一开始这可能看起来有点令人生畏，但这只是因为我放了太多#笔记。
这是带有纸币的版本

请知道我也是一个初学者，但我认为我们必须互相帮助，你知道吗？
因此，为了回答你的问题，像其他人所说的问题可以使用随机选择(列表(方法来解决
但我要指出的其他可以极大地缩短代码的事情是开始在类中学习。这比看起来容易得多，但类将允许您创建一个"玩家"类，该类具有名为score、name或card_drawn的对象，因此players.name='Mike'、players.score=27等。
我还重组了你的职能，并将其放在首位。这样你的实际游戏就可以分开了。我非常松散地认为函数是改变程序运行方式的标签。如果您曾经使用过命令提示符GOTO命令，那么它几乎可以以某种小的方式被视为相同的方式。只要函数已经定义，程序就会停止，并转到函数，无论它在哪里。
如果你有任何问题，请随时问我，你甚至可能也帮我解决一些问题。
