它在前五个区块运行良好,然后它只给我整个甲板的总值(95).我该如何解决？它应该只给我手中卡片的价值.我在这里做错了什么？

Answer 1

你的路线:

for hand in player_cards1:

可能没有做你期望它做的事情.看起来你认为它会比较hand和player_cards1; 相反,它所做的是在player_cards1上创建一个迭代器,你可以通过变量手来访问(意味着手被重新分配,并且将不再是['A','Q']).这是一个更简单的例子:

a = [1,2,3]
for item in a: //creates an iterator around a, with the variable item to refer to each list member
  print item

这三行计划将输出:

1
2
3

相反,你可能想要迭代手中的牌,例如:

for card in hand:
  //code here to look up the value of the card and add it to a running total

我还建议重新考虑你跟踪卡片值的方式,因为它会非常麻烦...提示:只有少数特殊情况你不能使用卡的面值.
