如何在字符串列表中搜索关键字并返回该字符串? [英] How to search for a keyword in a list of strings, and return that string?

问题描述

我有一个长度为几个单词的字符串列表，我需要搜索两个关键字，并返回包含这两个关键字的字符串.

I have a list of strings that are a few words long, and I need to search for two keywords, and return the strings that contain those two key words.

我曾尝试遍历字符串，但无法这样做.我尝试了 .find() 函数，但在字符串列表上没有成功.

I have tried to loop through the strings, but was not able to do so. I tried the .find() function but that was not successful on a list of strings.

假设我们有一个列表:

list = ["The man walked the dog", "The lady walked the dog","Dogs 
are cool", "Cats are interesting creatures", "Cats and Dogs was an 
interesting movie", "The man has a brown dog"]

我想遍历字符串列表并在包含单词man"和dog"的新列表中返回字符串.理想情况下，要获得以下内容:

I would like to iterate through the list of strings and return the strings in a new list that contain both the words "man" and "dog". Ideally, to get the following:

list_new = ["The man walked the dog", "The man has a brown dog"]

推荐答案

试试这个:

list_ = ["The man walked the dog", "The lady walked the dog","Dogs are cool", "Cats are interesting creatures", "Cats and Dogs was an interesting movie", "The man has a brown dog"]
l1 = [k for k in list_ if 'man' in k and 'dog' in k]

输出:

['The man walked the dog', 'The man has a brown dog']

注意:不要将变量名赋值为list.

Note : Refrain from assigning variable name as list.
