我正在尝试在python中编程卡游戏Euchre，并且我遇到了一些错误。我将在下面发布我的代码，然后解释我当前的问题：
import random

'''defines card class'''

#to define a numerical vaule to each card to determine which one wins the trick

到目前为止，我能够完成的是创建一个甲板，而四个球员中的每一个都被拿走了五张牌，然后让玩家询问他们想要玩什么卡。一旦他们玩了一张卡片，其他三名球员（两个对手和一个伴侣）演奏他们的卡片，然后我随机决定谁赢得了"技巧"，只是看得分是否正确。
我要解决的当前问题是，一旦玩家播放一张卡并播放了窍门，在下一个技巧上，他们在显示时应该少一张卡片，但我无法删除以前播放的卡片，以便播放器手里拿着五张卡。
你们中有人知道我在做什么错，以及如何删除选定的卡吗？感谢您的任何帮助。
您得到的IndexError是因为您使用了多个if S而不是elif。
if played_card==Player_hand[0]:
Player_hand.remove(Player_hand[0])
# The next if is still evaluated, with the shortened Player_hand
if played_card==Player_hand[1]:
Player_hand.remove(Player_hand[1])
使用：
if played_card==Player_hand[0]:
Player_hand.remove(Player_hand[0])
elif played_card==Player_hand[1]:
Player_hand.remove(Player_hand[1])
是的，使用您完成的那些类，然后使用__eq__进行比较。
