我得到一个 TypeError int object is not subscriptable 并且我的代码还没有完成我只想知道我的错误在哪里以及我该如何解决它，谢谢 :)

您的问题很简单：i 不可下标，因为 i 是值。在你修复你的下一个错误将是这部分 the_count += int(cards[0:1]) 之后，它应该是 the_count += i.

如果我们要进入脚本风格，那么我们可以完全重新开始。这是一款游戏，因此您首先需要的自然是游戏循环。接下来要做的就是 'play' 代码游戏。在二十一点中，庄家和玩家各执一词。游戏循环中发生的第一件事是庄家和玩家拿到牌。这两只手都已经有了一个值，所以我们立即获取它并一直保持更新。下一步是玩家选择被击中或站立。我们只需要知道'hit'。 'hit' 是唯一不是游戏结束的选择。最后，我们简单地比较分数以编造正确的消息并打印所有游戏属性。然后询问用户是否要 运行 再次循环。 'n' 或 'no' 以外的任何内容都是 'yes' ... 不管我们的小消息声称关于 'y'.

虽然@Michael Guidry 的回答是正确的，但我想以此为基础来解决样式问题。
您可以将 card_values 定义放在顶部的牌和手牌之前，因为它们还不相关。使用显式变量名更利于阅读和理解，因此我将 for i in the_hand: 替换为 for card in the_hand:。这些选项现在按照更容易理解的顺序排序（if ace/elif figures/else others 而不是 if figures or 10/elif not ace/else其他)。 hit/stand 选项现在包含在一个 while 循环中，以便在用户不回复 "H" 或 "S" 但不支持的情况下再次提出问题。
