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

报错

import urllib2

ImportError: No module named 'urllib2'

 

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

在python3.3里面，用urllib.request代替urllib2
