did you download this module from somewhere? there is a module called cfgparse that comes with Python distribution. you can use that. anyways, options are things like

...
[SECTION]
options = value
....

My friend, ghostdog74 is correct. The module is called configparser.

What you have is a RawConfigParser object created by:

config = ConfigParser.ConfigParser()

These objects are used to retrieve startup values (like window position, font selection, etc) from a file with a certain format. The idea (and the format, I think) come from Unix. On windows, the operating system keeps a database for us called The Windows Registry for this purpose.

The Python Manual says

"An application which requires initial values to be loaded from a file should load the required file or files using readfp() before calling read() for any optional files: "

import ConfigParser, os

config = ConfigParser.ConfigParser()
config.readfp(open('defaults.cfg'))
config.read(['site.cfg', os.path.expanduser('~/.myapp.cfg')])

So, in a file (say, '~/.myapp.cfg') there is a SECTION called "perforce" with option/value pairs that get read in to a dictionary by the syntax that you have given. Hope that helps.
