如何从方法列表中删除变量？

Question

我对Python相当陌生，我想知道如何解决问题。我正在进行基于文本的测验，以识别症状并确定您可能患有的疾病。我列出了一些包含症状的清单。然后，我针对每种疾病制定了一种方法（重复，我知道），以循环遍历症状并检查用户输入是否匹配。如果不是这样，我希望从可能的疾病列表中删除症状。但是请看，代码可以识别症状是否与第一个问题相匹配，但是即使将其删除，程序仍会在可能性列表中查找疾病。如果疾病不在可能的列表中，我尝试使用布尔变量来阻止程序循环。我试过使用可能的列表的for循环。我最近的尝试是将以前为Boolean的变量转换为字符串，然后以这种方式对其进行检查。就像我说的那样，我对Python还是很陌生，所以如果这是一个简单的错误，对不起。如果可以帮助，请执行！该项目应在星期五进行。非常感谢！

这里是代码（对不起，如果太长。Python的新手，网站的新手！）：]]

Answer 1

执行第一个ask（）后打印“可能”列表，检查列表中是否仍存在“ Herpangina”

Answer 2

如果您想为一位患者收集“是”和“否”，因为他们会回答是否有症状。并保持每种疾病的计数，您可以像这样遍历疾病/症状字典（symptom_dict）。
