There is the pickle module for serializing objects into strings: http://docs.python.org/lib/module-pickle.html If you need to store objects and later look them up by some key I would recommend using a database. There are plenty: http://docs.python.org/lib/persistence.html HTH, Daniel -- http://mail.python.org/mailman/listinfo/python-list
