How to run a ui converted python file in Qt-Creator

John R

I just learned only to convert a qt ui form file into python file by below cmd statement!

C:\Python27\Lib\site-packages\PyQt4\uic>pyuic4 -o "C:\QT Apps\testApp1\mainwindow.py"
"C:\QT Apps\testApp1\mainwindow.ui"

But don't know how to run this converted python file again from Qt creator or from Tk IDE.
I loaded "mainwindow.py" file into Qt creator using "File->NewFile or Project"
and tried to run this file using External->Python->RunPy but there is no output!
Something wrong in I am doing, somebody please help me on what I have to for running this converted py file,
please note the reference code below
