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=‘http://news.gzcc.cn/html/xiaoyuanxinwen/‘

res=requests.get(url)
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
        time=news.select(‘.news-list-info‘)[0].contents[0].text
        url=news.select(‘a‘)[0][‘href‘]
        thumb=news.select(‘.news-list-thumb‘)[0].contents[0]
        print(time)
        print(title)
        print(url)
        print(thumb)

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://sports.qq.com/nba/‘
res = requests.get(jq)
res.encoding=‘utf-8‘
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)
