system command

[Jack B.]

I am trying to execute a system command within my python/Tkinter
program, but I do not want to wait for it to exit.  It will  launch a
different Tkinter program to be run at the same time.  This seems like
it should be simple, but I cannot find a way to do it.  Help please,
thanks!

In Perl, this would be very simple.  But perhaps it is simple in
Python and I just have not found it yet.
