This will be excellent, Terry.

For the present case, perhaps we should also point out that in
python 3.0:

" Note

The formatting operations described here are obsolete and may go away in 
    future versions of Python. Use the new String Formatting in new code."

(Taken from the provisional documentation at:

http://docs.python.org/dev/3.0/library/stdtypes.html#old-string-formatting
)
