从文件中提取特定单词

Question

我正在分析一些文本文件，每次在文件中找到该词时，我都想提取一个特定的词。想象一下，我在文件中有“体育”，然后我想根据列表提取单词“体育”。我有以下代码：content = ['Sports', 'Nature', 'Football']path = filenamewith open(path) as auto:    for line in auto:        if any(x.lower() in line.lower() for x in content):            print(line)我的文本文件有以下内容：Sports TV is the home of football videos. Complex game to follow.home of football用我的代码打印所有带有“体育”和“足球”的行：Sports TV is the home of football videos. home of football但我想看到以下结果：Sportsfootball如何仅打印 List 上的单词而不是所有行？

Answer 1

列表.txt：

Sports TV is the home of football videos. 

Complex game to follow.

home of football

因此：

content = ['Sports', 'Nature', 'Football']

path = 'list.txt'

with open(path) as auto:

    print([[x.lower() for x in content if x.lower() in line.lower()] for line in auto])

输出：

[['sports', 'football'], [], ['football']]

由于：

第 1 行有sports和football

第 2 行没有来自内容列表的匹配元素

第 3 行有 football

Answer 2

您目前正在打印整行

尝试：

content = ['Sports', 'Nature', 'Football']

path = filename

with open(path) as auto:

    for line in auto:

        for x in content:

            if x.lower() in line.lower():

                print(x)
