Python2.2 in Linux RH7.2 - Newbie

[Ahimsa Consulting]

Hi folks
I am dealing with a double whammy here: I am new to both Python and Linux.
I have been able to call Python up in the Linux console in interactive mode
i.e. '>>>'. I don't seem able to call up tkinter. Now I am probably doing
something incorrectly. If someone could be kind enough to walk me through
this process in baby steps bearing in mind my newbie status.

Thanks
Andrew
