This is probably what he meant:

$ py

Python 2.7.8 |Anaconda 2.1.0 (64-bit) ... on win32

>>> import bsddb

>>> print bsddb.__doc__

Support for Berkeley DB 4.3 through 5.3 with a simple interface.

For the full featured object oriented interface use the bsddb.db module instead. It mirrors the Oracle Berkeley DB C API.

bsddb is deprecated as of python 2.6 and removed in python 3

That particular back-end is deprecated, but the same API is provided by the dbm/gdbm/dumbdbm modules. Those still exist in Python 3, although they've been consolidated under one top-level module.

also, no unicode keys for this or shelve in 2.7 which really causes some coding pain. (not sure about 3.X)

Ahhh... Thanks, never knew that!
