我遇到了一些问题。在我的代码中，我将编写一个用于诊断患者的“图灵测试”。我真的认为这比我写作更简单。我甚至没有这样做。当我运行程序时，无论我选择什么，我都会继续获得第一个选项。我似乎无法让我的程序停止运行。我试过quit，break，exit，sys.exit，sys.exit（）和sys.exit（0）。所以我的问题是：“有更简单的方法吗？”，“我的if和elif语句出错了什么？”，“当用户不想继续时，如何使程序结束？ “谢谢！
（我的计划尚未完成，但你明白了）

答案 0 :(得分：5)
您拥有的所有条件都将评估为True，因为您正在评估字符串 "Head"的“真实性”，{{1} } 等等。您想要的是将这些字符串与输入请求的结果进行比较。
"Scalp"至于“我做得对吗”，你的逻辑似乎一目了然。但是，肯定有更容易的方式来做你正在做的事情。我最简单的想法是使用字典来保存所有可能的诊断路径：将其视为“树”（事实上，如果您还没有这样做，我建议绘制decision tree）。然后，您可以将“树”嵌入Python字典中，只需使用字典键填写模板字符串（area = raw_input ("Which area hurts? Head, Neck,...")
if area == "Head":
head_area = raw_input("Where does your head hurt?...")
# etc
else:
# etc
和"Which area hurts? ..."）。
我的意思的一个非常简短的例子：
"It is possible that..."答案 1 :(得分：1)
您要求raw_input()输入，但您没有存储用户Feed！
你应该存储这个价值＆amp;然后对其进行if ... else。
东西，如下面
area = raw_input("Where does it hurt?")
if area == "chest":
# do/ask something related to chest
elif area == "neck":
# do/ask something related to neck
...
else:
print ("Please specify one of these - chest/neck/...")
此外，您可以将问题存储在开头的变量中。然后通过变量使用它们，这样你的代码看起来就更好了。
ques_area = "Which area hurts? Head, Neck, Chest, Abdomen, Back, Arms, Legs, Buttocks, Pelvis, or none: "
ans_area = raw_input(ques_area)
