我导入以下文件 但得到这个错误类BJ_Card（cards.deck）： TypeError：调用元类库时出错 list（）最多需要1个参数（3个给定）这是我第一次写一个程序并花了一些时间修复其他问题，但这个我只是想不通。请帮忙。
import random

# second letter represents the suit
deck = ['AH','2H','3H','4H','5H','6H','7H','8H','9H','TH','JH','QH','KH',

答案 0 :(得分：0)
我认为问题可能是您的__init__课程中没有BJ_Card(cards.deck)方法。
此外，您正试图通过调用
来初始化新的卡片对象self.cards.append(BJ_Card(rank, suit))
当BJ_Card既不接受rank也不接受suit
试试这个：
class BJ_Card(cards.deck, rank, suit):
""" A Blackjack Card. """
ACE_VALUE = 1
super(cards.deck, self).__init__('''whatever you need to pass here ''')
@property
def value(self):
if self.is_face_up:
v = BJ_Card.RANKS.index(self.rank) + 1
if v > 10:
v = 10
else:
v = None
return v
