Python “如何写入此脚本以验证结束”；如果他们想退出此计划”；

需要在最后说“你想退出吗”并选择“是”或“否”，然后在输入后说“你确定吗”，如果有其他选择，则说“是”或“否”无效输入并再次提问。

写得更像pythonic:

problem = False
while problem == False:
    foo = open("solutions.txt","r")
    print("What is wrong with your device?")
    issue=input()

    if (('wet' in issue) and ('water' in issue)):
        solutions = foo.readlines()
        print(solutions[0]+solutions[1])
        problem = True

       # (and so on).

首先，请注意，您可以简单地使用带有True的永久while循环，并在需要时中断循环，或者作为一个问题并中断循环，答案是否定的。其次，对于打开文件，您最好使用

和

语句，在块的末尾自动关闭文件。如果你的文件很大，你最好使用

readline

方法来读取前两行。

循环中的下一行是：

while True:
    with open("solutions.txt") as foo:
        issue = input("What is wrong with your device?")
        if 'wet' in issue and 'water' in issue:
            print(foo.readline() + foo.readline())
        question = input("Do you want to continue? (Y/N)")
        if question == 'N':
           break

 answer = raw_input("Would you like to exit?  Enter 'Yes' or 'No': ")
 while answer not in ["Yes","No"]:
     answer = raw_input("Would you like to exit?  Enter 'Yes' or 'No': ")
 if answer == "Yes"
     problem = True    # This will cause you to exit the loop
