python百度爬虫关键词python

以下是一个使用Python编写的爬取百度新闻中包含关键词"python"的爬虫示例：

import requests
import re

def baidu_news_spider(keyword):
    url = 'https://www.baidu.com/s?wd=' + keyword + '&tn=news&ie=utf-8'
    headers = {
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'}
    response = requests.get(url, headers=headers)
    content = response.text
    pattern = re.compile('<h3 class="c-title">.*?<a.*?href="(.*?)".*?>(.*?)</a>', re.S)
    results = re.findall(pattern, content)
    for result in results:
        news_title = result[1]
        news_url = result[0]
        print(news_title, news_url)

# 调用爬虫函数，传入关键词"python"
baidu_news_spider('python')

这个爬虫示例使用requests库发送HTTP请求，通过正则表达式解析爬取的数据，然后打印出新闻标题和链接。
