Names (and their ojects) may be looked up
from the names/attributes of the default bound objects (at least, zope 2.5.0):
context, container, script, traverse_subpath

when your script is called, these are defined.
context is the caller (usually some zpt/dtml-document),
container the containing folder

as these objects are objects in data.fs,
data.fs is an object collection organized as a tree
(ObjectManager is one of the base classes of Folder),
close to any object (and its attributes) are accessible from your py script
(security aside).
execution pereforms in a restricted environment,
the zope book dtml-appendix contains a list of restricted code.
