• 用requests库和BeautifulSoup4库，爬取校园新闻列表的时间、标题、链接、来源。

　　import urllib.request as urllib2
from bs4 import BeautifulSoup
url=\'http://news.gzcc.cn/html/xiaoyuanxinwen/\'
request=urllib2.Request(url)
response=urllib2.urlopen(request)
bsObj=BeautifulSoup(response.read(),"html.parser")
for i in bsObj.select(\'li\'):
    if len(i.select(\'.news-list-title\')) > 0:
        time = i.select(\'.news-list-info\')[0].contents[0].text
        source=i.select(\'.news-list-info\')[0].contents[1].text
        title = i.select(\'.news-list-title\')[0].text
        describe=i.select(\'.news-list-description\')[0].text
        url = i.select(\'a\')[0][\'href\']
        print(time,title,url,describe)

　　

 

• 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=%E7%8F%A0%E6%B5%B7\')
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)
