The os module is not going away although the popen 
function might some day.

However subprocess is currently the recommended way 
to do subprocess control and is more powerful and flexible 
than popen.

Did you see the subprocess documentation page that 
shows how to do the equivalent of popen etc? 
Look down to section 18.1.3.5
