title: Building a window application from the bunch of python files
body: <p>I have written some bunch of python files  and i want to make a window application from that. 
  The structure looks like this:
  Say, a.py,b.py,c.py are there. a.by is the file which i want application to open and it is basically a  GUI which has import commands for "b.py" and "c.py". 
  I know this might be a very basic problem,but i have just started to packaging and deployment using python.Please tell me how to do that , or if is there any way to do it by py2exe and pyinstaller?</p>
  
  <p>I have tried to do it by py2exe and pyinstaller from the info available on internet , but that seems to create the app which is running only "a.py" .It is not able to then use "b" and "c " as well.</p>
