1. #获得贴吧的标题
   
2. 
   
3. import urllib.request
   
4. import re
   
5. 
   
6. def url_open(url):
   
7.     #伪造headers 防止屏蔽
   
8.     head = {}
   
9.     head['User-Agent'] = 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36'
   
10. 
    
11.     req = urllib.request.Request(url,headers=head)
    
12.     response = urllib.request.urlopen(req)
    
13.     html = response.read().decode('utf-8')
    
14.

20.     for title in info:
    
21.         print(title)
    
22. 
    
23. if __name__=='__main__':
    
24.     for i in range(5):
    
25.         ii = (i+1)*50
    
26.         print(ii)
    
27.         url = "http://tieba.baidu.com/f?kw=%E5%B1%B1%E4%B8%9C%E9%B2%81%E8%83%BD&ie=utf-8&pn=" + str(ii)
