[Tutor] Saving class instances

[Daniel Woodhouse]

I think you are better off using a database in this situation, sqlite3 is a
good choice since no extra setup is required. See
http://docs.python.org/library/sqlite3.html

And to answer your question, the python pickle module can save class
instances, see http://docs.python.org/library/pickle.html
