为什么我不能让Python的urlopen()方法在Windows上工作?

为什么这个简单的Python代码不起作用?

import urllib
file = urllib.urlopen('http://www.google.com')
print file.read()

这是我得到的错误:

Traceback (most recent call last):
  File "C:\workspace\GarchUpdate\src\Practice.py", line 26, in <module>
    file = urllib.urlopen('http://www.google.com')

我试过用几页不同的纸,但我永远也找不到答案 urlopen
