有没有办法检查列表中的字符串是否包含来自另一个列表的任何子字符串？

Question

I have two lists of strings, list_1 and list_2.

list_1 = ["Hello", "Hi", "Hey"]
list_2 = ["Hello, my name in John.", "Hi, my name is John.", "Hey, my name 
           is John.", "My name is John."]

I want to check if any of the strings in list_1 are contained in any of the strings in list_2, in such a way that returns the strings in list_2 for which this is true. Is there a good way to do this?

Answer 1

You can use the any function with a generator expression as a filter condition of a list comprehension:

[s for s in list_2 if any(k in s for k in list_1)]

This returns:

['Hello, my name in John.', 'Hi, my name is John.', 'Hey, my name is John.']
