在文件中搜索作为问题的句子

Question

f = open("data.txt", "rt")
lines = f.read()
#word = line.split()
for line in lines:
    if line == 'how' or line == 'what' or line == 'where':
        print(lines, "Yes")
    else:
        print(lines, "No")
f.close()

我正在尝试阅读一个文件并寻找包含如何、什么、在哪里等的句子。基本上是一个问题的句子。并相应地打印句子以及是或否。

Format of Input file: 
how are you 
it's 7 o'clock  
where is your food

Format of Output file:
how are you  Yes
it's 7 o'clock  No
where is your food Yes

但是我的代码没有输出。

行 if line == 'how' or line == 'what' or line == 'where': 向我建议您可能想要使用关键字逻辑 any():

f = open("data.txt", "rt")
lines = f.readlines()
f.close()

with open('data_out.txt', 'w') as f:
    for line in lines:
        if any(question_word in line for question_word in ['how', 'what', 'where']):
            output = '{} {}\n'.format(line.strip('\n'), "Yes")
            print(output)
            f.write(output)
        else:
            output = '{} {}\n'.format(line.strip('\n'), "No")
            print(output)
            f.write(output)

how are you  Yes
it's 7 o'clock   No
where is your food Yes
