Question

我正在分析一些文本文件，因此我希望每次在文件中找到一个单词时都提取一个特定的单词。

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)

我的文本文件具有以下内容：

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

使用我的代码，我将“ Sports”和“ Football”的所有行打印出来：

Sports TV is the home of football videos. 

home of football

但是我想看到以下结果：

Sports
football

如何仅打印列表中的单词而不是所有行？

谢谢！

Answer 1

list.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']]

自开始：

第1行有sports和football

第2行的内容列表中没有匹配的元素

第3行有football

Answer 2

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)
