我正在分析一些文本文件，并且每次在文件中找到该单词时，我都想提取该特定单词。

想象一下，我在文件中有“Sports”，然后我想根据列表提取单词“SPORTS”。

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)

我的文本文件包含以下内容：

Sports TV is the home of football videos. 
Complex game to follow.
home of football

使用我的代码，我打印所有带有“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？

谢谢！

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']]

自：

第 1 行有sports和football

第 2 行没有来自内容列表的匹配元素

3号线有football

您现在正在打印整行

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)
