[pygtk] Getting password and running command-line with privileges

[Juan Fiol]

Hi,
I am implementing a gui and I need to implement it such that, in some
occasions, the user can run a command with privileges (via sudo). I
implemented a text entry with "no visible"  property to insert the
password and then I am running the command as:

os.system("cat password | command")

Is there a better (right way) to do it? Where may I find
hints/examples/discussion on how to implement this?

Thanks
        Juan
