我得到一个 TypeError int object is not subscriptable 和我的代码是未完成的，我只是想知道我的错误在哪里，我怎么能解决它，谢谢:)
Traceback (most recent call last):
File "C:\Users\TOSHIBA\.spyder-py3\untitled1.py", line 40, in <module>
print('You have:' , card_values(player_hand)) # telling the player's value if he stands
File "C:\Users\TOSHIBA\.spyder-py3\untitled1.py", line 19, in card_values
if (i[0:1] == 'J' or i[0:1] == 'Q' or i[0:1] == 'K' or i[0:1] == 10):
TypeError: 'int' object is not subscriptable
这是我得到的错误

虽然 @Michael Guidry 的答案是正确的，但我想在此基础上解决风格问题。
你可以把 card_values 的定义，因为这些还不相关。使用显式的变量名更有利于阅读和理解，所以我用了 for i in the_hand: 与 for card in the_hand:. 现在选择的顺序更容易理解 (if aceelif figureselse others 而不是 数字或10elif not aceelse others). 现在，hitstand的选择被封装在一个while循环中，以在用户没有回答 "H "或 "S "但不支持的东西时，再次提问。
import random # Importing random function.
def card_values(the_hand):
"""This function calculate the values of a given hand."""
the_count = 0
ace_count = 0
for card in the_hand:
if card == "A":
ace_count += 1
elif card in ("J", "Q", "K"):
the_count += 10
else:
the_count += card
if ace_count == 1 and the_count <= 10:
the_count += 11
elif ace_count != 0:
the_count += 1
return the_count

你的问题很简单。i 你的问题很简单： i 是值。在你解决了这个问题之后，你的下一个错误将是这部分内容 the_count += int(cards[0:1]) 应是 the_count += i.

如果我们要进入脚本的风格，那么我们可以完全重新开始。这是一个游戏，所以，你首先需要的自动是一个游戏循环。接下来要做的就是简单地用代码 "玩 "这个游戏。在21点游戏中，庄家和玩家拿到一手牌。在游戏循环中，首先要发生的是庄家和玩家拿到一手牌。这两手牌都已经有了一个值，所以我们立即得到它，并一直保持更新。下一步是玩家选择中牌或站牌。我们只需要知道'中'。'hit'是唯一不是游戏结束的选择。最后，我们只需要比较分数来编造合适的信息，并打印所有的游戏属性。然后我们会问用户是否要再次运行这个循环。除了'n'或'no'之外的任何其他选项都是'yes'......不管我们的小信息是否有'y'的说法。
