The current version of PL/Python functions as a trusted language
only; access to the file system and other local resources is
disabled. Specifically, PL/Python uses the Python restricted
execution environment, further restricts it to prevent the use of
open call, and allows only
modules from a specific list to be imported. Presently, that list
includes: array, bisect, binascii,
calendar, cmath, codecs, errno, marshal,
StringIO, struct, time, whrandom, and zlib.
