用requests库和BeautifulSoup4库爬取新闻列表

Posted 2020-10-08 风一样的浪子

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)
