Look at pickle, but I'd recommend against it if you're anticipating
needing to edit the file by hand.  It's just a little on the ugly side.
 Glance at Yaml (I think it's the pyyaml project in the cheeseshop) as
well.  Here's the code needed to "parse" in a .yaml file:

config = yaml.load(open(self.config_file, "r"))

Here's the code needed to serialize it back in a pretty format:

yaml.dump(config, config_file_obj, default_flow_style=False)

And here's a piece of a .yaml file itself:
