一、爬取校园新闻


import requests   
from bs4 import BeautifulSoup 
url = requests.get("http://news.gzcc.cn/html/xiaoyuanxinwen/")
url.encoding = "utf-8"
soup = BeautifulSoup(url.text,'html.parser')
#print(soup.head.title.text)
 
for news in soup.select('li'):
    if len(news.select('.news-list-title'))>0:
        #print(news.select('.news-list-title'))          
        #print(news.select('.news-list-title')[0])       
        #print(news.select('.news-list-title')[0].text)  
        time = news.select('.news-list-info')[0].contents[0].text 
        title = news.select('.news-list-title')[0].text           
        href = news.select('a')[0]['href']                        

        href_text = requests.get(href)                            
        href_text.encoding = "utf-8"
        href_soup = BeautifulSoup(href_text.text,'html.parser')
        href_text_body = href_soup.select('.show-content')[0].text
        print(time,title,href,href_text_body)

二、爬取自己兴趣的网页


import requests
from bs4 import BeautifulSoup
jq='http://www.gamersky.com/pcgame/'
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)
