You can save and restore objects using the 'pickle' module:
# create new object 'j'
j = Struct()
j.name = 'john'
j.title = 'stud'
# package it up
x = pickle.dumps(j)
# "x" is a semi-printable representation of object "j":
# => looks something like "(i__main__ Struct p0
# (dp1 S'title' p2 S'stud' p3 sS'name' p4 S'john' p5 sb."
z = pickle.loads(x)
# "z" is a new object, loaded from "x", which is a
# copy of our original object. To test it, print out its name.
# => "john"
Also check out the shelve and binascii modules.
