Oops sorry I did not say where to put it! Use the Jython library
in the IDV itself : menu choice 
Edit->Jython library, user library pane. You can enter and edit Jython
code there.

Any methods in the IDV jython library can be called directly by your
formulas.
The Jython library is a way to create code more complex than a one-line
formula.
