I'm not sure that I understand what you are trying to do.
But trying to replace cmd.exe is a very very bad idea.
Lots of bits of your operatinfg system rely on cmd.exe
and bad things are likely to start happening!

Same as any other function:

retval = os.system('notepad.exe')

Sorry, that didn't clarify anything for me! :-)

Are you trying to write your own operating system shell
environment (to use instead of cmd.exe)? Are you trying to
write a Python based command shell? Or are you trying
to create your own IDE?

I'm confused.
