It can store and retrieve almost any Python object with almost no effort. Up to you whether you see it as an advantage to be able to store objects rather than (almost) pure data with a rather limited type set. Of course, "pickle" is a proprietary Python format. Not so easy to decode it with something else than Python. In addition, when you store objects, the retrieving application must know the classes of those objects -- and its knowledge should not be too different from how those classes looked when the objects have been stored. I like very much to work with objects (rather than with pure data). Therefore, I use "pickle" when I know that the storing and retrieving applications all use Python. I use pure (and restricted) data formats when non Python applications come into play. -- http://mail.python.org/mailman/listinfo/python-list
