import requests from bs4 import BeautifulSoup from datetime import datetime utl = 'http://news.gzcc.cn/html/xiaoyuanxinwen/' res = requests.get(utl) res.encoding= 'utf-8' soup = BeautifulSoup(res.text,'html.parser') for i in soup.select('li'): if len(i.select('.news-list-title')) > 0: f = i.select('.news-list-info')[0].contents[1].text t = i.select('.news-list-title')[0].text h = i.select('a')[0].attrs['href'] resd = requests.get(h) resd.encoding = 'utf-8' soupd = BeautifulSoup(resd.text, 'html.parser') zw = soupd.select('#content')[0].text info = soupd.select('.show-info')[0].text dt = info.lstrip('发布时间:')[0:19] p = datetime.strptime(dt, '%Y-%m-%d %H:%M:%S ') print(f,t,h,zw,p)
