如何在列表中查找元素,该元素是Python中另一个列表中另一个元素的一部分

Question

我有这个清单:

dc = ["hello", "world"]

而另一个:

lines = ["This is", "an example of hello", "line in the world of strings", "Testing"]

我希望在直流上找到那些属于线条任何元素的元素......

我可以将行循环为:

for line in lines:
    # what to do here?

但我不知道如何确切地找到dc中的"hello"元素可以在"hello的例子"中找到,或者在"字符串世界中的行"中找到dc中的"world"在线......

也许我不应该循环线？

Answer 1

>>> dc = ["hello", "world", "foo"]
>>> lines = ["This is", "an example of hello", "line in the world of strings", "Testing"]
>>> [word for word in dc if any(word in line for line in lines)]
['hello', 'world']
