用requests库和BeautifulSoup4库爬取新闻列表
1、用requests库和BeautifulSoup4库,爬取校园新闻列表的时间、标题、链接、来源。
import requests from bs4 import BeautifulSoup res=requests.get('http://news.gzcc.cn/html/xiaoyuanxinwen/') res.encoding='utf-8' soup=BeautifulSoup(res.text,'html.parser') for news in soup.select('li'): if len(news.select('.news-list-title'))>0: title=news.select('.news-list-title')[0].text url=news.select('a')[0]['href'] time=news.select('.news-list-info')[0].contents[0].text laiyuan=news.select('.news-list-info')[0].contents[1].text print(title,url,time,laiyuan)
2、选一个自己感兴趣的主题,做类似的操作,为“爬取网络数据并进行文本分析”做准备。
import requests from bs4 import BeautifulSoup res=requests.get('http://trips.tuniu.com/search?q=%E9%9F%B6%E5%85%B3') res.encoding='utf-8' soup=BeautifulSoup(res.text,'html.parser') for trips in soup.select('li'): if len(trips.select('.list-name'))>0: title=trips.select('.list-name')[0].text url=trips.select('a')[0]['href'] print(title,url)
