Question

当用户输入短语时，短语中的关键词需要与文本文件中的文本匹配，然后文本文件中的行可以打印回给用户。

e.g。当用户输入“我的手机屏幕为空白”或“显示屏为空白”时，应该有相同的解决方案从文本文件输出到屏幕。

searchfile = open("phone.txt", "r")

question = input (" Welcome to the phone help center, What is the problem?")
  if question in ["screen", "display", "blank"]:
        for line in searchfile:
            if question in line:
                print (line)


elif question in ["battery", "charged", "charging", "switched", "off"]:
        for line in searchfile:
            if question in line:
                print (line)

            else:
                if question in ["signal", "wifi", "connection"]:
                    for line in searchfile:
                        if question in line:
                                print (line)

searchfile.close()

在文本文件中：

屏幕：您的屏幕需要更换电池：您的电池需要充电信号：您没有信号

Answer 1

您可以使用raw_input

以下是工作代码：

search_file = open(r"D:\phone.txt", "r")

question = raw_input(" Welcome to the phone help center, What is the problem?")
if question in ["screen", "display", "blank"]:
    for line in search_file:
        if question in line:
            print (line)


elif question in ["battery", "charged", "charging", "switched", "off"]:
        for line in search_file:
            if question in line:
                print (line)
else:
    if question in ["signal", "wifi", "connection"]:
        for line in search_file:
            if question in line:
                print (line)

search_file.close()

Answer 2

首先，这2行不符合您的要求：

question = raw_input(" Welcome to the phone help center, What is the problem?")
if question in ["screen", "display", "blank"]:

如果用户输入我的手机屏幕为空，因为完整句子不是列表的成员，其余的if将不会被执行。您应该测试句子中是否存在列表的任何成员：

question = raw_input(" Welcome to the phone help center, What is the problem?")
for k in  ["screen", "display", "blank"]:
    if k in question:
        for line in searchfile:
            if k in line:             # or maybe  if 'screen' in line ?
                print line
                break
        break
