Depends. If you are concerned about security, this will be hard to achieve in
Python. I imagine that this could be related to cheating prevention.

If you are more concerned about namespace polution and making only a well
defined API available to the scripts, go the module-import way and hand some
API object over, either through an initialisation function or by injecting it
into the module namespace, as Arnaud suggested.
