How to Extract List Items Matching Multiple Keywords in Python

Introduction

In response to a follower's question about extracting list elements that contain both "python" and "应用" (application) keywords, the author demonstrates two Python solutions.

Method 1: Regular List Access

# -*- coding: utf-8 -*-
# Method 1
keywordlist = ['python', '应用']
title = [['人生苦短，我应用python'], ['Rick Xiang 666'], ['歪歪nb'], ['为才哥打call'], ['网络爬虫的应用']]
for luwen in title:
    if keywordlist[0] in luwen[0] and keywordlist[1] in luwen[0]:
        print(luwen)

The code iterates over the nested list, checks both keywords, and prints the matching sub‑list.

Method 2: Using the operator Module

# -*- coding: utf-8 -*-
import operator
keywordlist = ['python', '应用']
title = [['人生苦短，我应用python'], ['Rick Xiang 666'], ['歪歪nb'], ['为才哥打call'], ['网络爬虫的应用'], ['python爬虫与数据挖掘']]
for luwen in title:
    if operator.contains(luwen[0], keywordlist[0]) and operator.contains(luwen[0], keywordlist[1]):
        print(luwen)

This approach uses operator.contains to perform the same check.

Conclusion

The article shows two straightforward ways to filter a list of strings by multiple keywords, helping the asker solve the problem and encouraging readers to explore additional methods.
