在python2.x版本中可以直接使用import urllib来进行操作，但是python3.x版本中使用的是import urllib.request来进行操作，下面是简单的例子：

 

python2.x

  

import urllib  url = 'http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing=12345'  text = urllib.urlopen(url).read()

　　

python3.x

 

import urllib.request  url = 'http://www.pythonchallenge.com/pc/def/linkedlist.php?nothing='  current = '12345'  response = urllib.request.urlopen(url+current)  text = response.read()  current = text[-5:]  response = urllib.request.urlopen(url+current)
