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 url_main="http://news.gzcc.cn/html/xiaoyuanxinwen/" res = requests.get(url_main) res.encoding = ‘utf-8‘ soup = BeautifulSoup(res.text,‘html.parser‘) li = soup.select(‘li‘) for li_title in li: if len(li_title.select(‘.news-list-title‘))>0: herf = li_title.select(‘a‘)[0][‘href‘] title = li_title.select(‘.news-list-title‘)[0].text time = li_title.select(‘span‘)[0].text info = li_title.select(‘span‘)[1].text li_res = requests.get(herf) li_res.encoding = ‘utf-8‘ li_soup = BeautifulSoup(li_res.text,‘html.parser‘) li_text = li_soup.select(‘.show-content‘)[0].text print(time,title,herf,info,‘\n‘,li_text)
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 jq=‘http://news.qq.com/l/milite/milgn/list2010122872223.htm‘ res = requests.get(jq) res.encoding=‘gb2312‘ soup = BeautifulSoup(res.text,‘html.parser‘) for news in soup.select(‘li‘): if len(news.select(‘a‘))>0: title=news.select(‘a‘)[0].text url=news.select(‘a‘)[0][‘href‘] #time=news.select(‘span‘)[0].contents[0].text #print(time,title,url) print(title,url)
