python3.3 urlopen失败？

import tkinter
import urllib
class Window:
    def __init__(self,root):
        self.root = root
        self.entryUrl = tkinter.Entry(root)
        self.entryUrl.place(x=5,y=13)
        self.get = tkinter.Button(root,text='xia',command= self.Get)
        self.get.place(x=120,y=13)
        self.edit = tkinter.Text(root)
        self.edit.place(y=50)
    def Get(self):
        urlq = self.entryUrl.get()
        page = urllib.urlopen(urlq)
        data = page.read()
        self.edit.insert(tkinter.END,data)
        page.close()
root = tkinter.Tk()
window = Window(root)
root.minsize(600,800)
root.mainloop()

提示

Exception in Tkinter callback

Traceback (most recent call last):

  File "C:\Python33\lib\tkinter\__init__.py", line 1442, in __call__
    return self.func(*args)
  File "C:\Documents and Settings\Administrator\桌面\d.py", line 14, in Get
    page = urllib.urlopen(urlq)
AttributeError: 'module' object has no attribute 'urlopen'

urlopen怎么会找不到呐？很郁闷

找到问题了，原来导入的时候要用

import urllib.request
