These are fine suggestions, but there is a third option. Under the ZMI, go


Summary: You can define a null product that just imports modules you want to
use. Those modules are then available for Python Script objects. The
document only discusses standard modules (re, base64, etc) but I'm assuming
that your bog-standard modules should work fine too.

FWIW, I actuall suggest #2 below if you intend to go into production, since
that will give you the best security model. My suggestion above would be
good if the module is simple and obviously secure (is there such a thing?)
or you never intend to put your server into a hostile environment, such as
the Wooly Wild Web.
