The import requests
The import hashlib
The import time


Def get_index (url) :

If respose. Status_code==200:
Return respose. Text

Def parse_index (res) :

Return urls

With the open (filepath, 'wb) as f:
F.w rite (video content)




Def the main () :
For I in range (5) :
Res1=get_index (' http://www.xiaohuar.com/list-3-%s.html '% I)

The program will then run in PyCharm, results suggest:
