python3报错：No module named 'urllib2'

Python 3.3之后，urllib2改为urllib.response

Python 2.7 代码：

import urllib2   response = urllib2.urlopen('http://www.baidu.com/')   html = response.read()   print html   

Python 3.3 代码应该为：

import urllib.request response=urllib.request.urlopen('http://www.baidu.com') html=response.read() print(html)
