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 = filename

with 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：

Sports

football

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 = filenamewith open(path) as auto:    for line in auto:        for x in content:            if x.lower() in line.lower():                print(x)
