IMHO this statement is a bit too broad. The original poster didn't
specify that he wanted to become root.
Running a command as a different user is useful for other cases
besides running as root. For instance, your web server's documents
directory may be owned by a www user who doesn't have a normal login
shell. If you're on your 'regular' user and need to edit a document
it's quite handy to do this:
sudo -u www emacs index.html
As for the original poster, you could use the subprocess module
combined with sudo to do what you want - spawn a subprocess which runs
sudo and the other program, which could itself be a python script or
anything else.
