Pickling is also very useful when combined with the bsddb module, because you get a fast database which functions very much like a dictionary, and in which you can put anything you like, as long as you pickle it first.
import bsddb mydb = bsddb.btopen('game.db') mydb['highscores'] = pickle.dumps(mylist) mydb['highestlevel'] = pickle.dumps(21) mydb['lastplayer'] = pickle.dumps('John Doe') mydb.close() mydb = bsddb.btopen('game.db') pickle.loads(mydb['lastplayer'])
'John Doe'
You might be interested in the shelve module which essentially does this for you. With shelve your example would look like this:
import shelve
d = shelve.open('game.db')
d['highscores'] = mylist
d['highestlevel'] = 21
d['lastplayer'] = 'John Doe'Kent
