PyQt4 window does not appears while running the program but appears on ipython

I was trying out PyQt4. and tried this code.

import sys                                                                    
from PyQt4 import QtGui                                                       

app = QtGui.QApplication(sys.argv)                                            
window = QtGui.QWidget()                                                      
window.show()  
print 'end'

This above code works when i try it on on ipython , But it doesn't when i write them into a file and run it. I also tried changing the permission by chmod +x . The code actually runs(the reason i added a print statement at the end to confirm if the code is running till the end), i don't get a window.

im running python 2.7.6 on ubuntu 14.04

初始化小部件并在主窗口上调用show() ,需要通过调用app.exec_()启动Qt事件循环。
