In Python, they are build in.
Aren't they in PythonScripts?
They should be (this is a wish).

You can selectively (unfortunatly only globally) allow import.
The list archive will tell you the details.

It is something like (in a product):

   import module; module.__allow_access_to_unprotected_objects=spec

   with "spec" set to "1" for unrestricted access to all module
   variables and "spec" set to a dictionary mapping to "1"
   for controlled access.
