在文本文件中搜索与从用户Python输入的文本匹配的文本行

Question

当用户输入短语时，短语中的关键字需要与文本文件中的文本匹配，然后可以将文本文件的行打印回用户。

例如，当用户键入"我的手机屏幕为空白"或"显示屏为空白"时，应该从文本文件向屏幕输出相同的解决方案。

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：你的屏幕需要更换电池：你的电池需要充电信号：你没有信号

Answer 1

首先，这两行不符合您的要求：

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

如果用户键入我的手机屏幕为空，因为整句话不在列表中，则不会执行If的其余部分。相反，你应该测试句子中是否存在列表中的任何成员：

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

Answer 2

您可以使用raw_input

这是工作代码：

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()
