Root access with python

[Moray Taylor]

Hi,

I want to know how to run a 'root' command with python, i.e. mounting
an NFS drive.

On the terminal, you would do a 'su', type your password, then enter
the command you wanted to run. How is this achieved within Python?

My purpose is to make a small GUI app with PyQT to make mounting NFS 
volumes easier, I can handle the GUI bit, but I don't understand how
to 'su'.

Thanks  for any help
