import requests

import sys


type = sys.getfilesystemencoding()

headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)\
Chrome/55.0.2883.87 Safari/537.36'}
html = requests.get('http://vip.iqiyi.com/hot.html?cid=1',headers=headers)
html.encoding = 'utf-8'

讲来讲去，还是正则表达式没有写对：

1. import requests
   
2. import re
   
3. import sys
   
4. 
   
5. 
   
6. type = sys.getfilesystemencoding()
   
7. 
   
8. headers = {'User-Agent':'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko)\
   
9. Chrome/55.0.2883.87 Safari/537.36'}
   
10. html = requests.get('http://vip.iqiyi.com/hot.html?cid=1',headers=headers)
    
11. html.encoding = 'utf-8'
    
12. title = re.findall(r'<a target="_blank" rseat="709181_热播榜二级页_电影(.*?)" title="(.*?)"',html.text,re.S)
    
13. for each in title:
    
14.     print(each)

正则表达式那少写了一个r吗？为什么一定要加呢
