If you have control over the config file format you can use ConfigParser 
in the standard lib. It reads .ini style files so you would write
[apache]
process=/usr/bin/httpd
...etc

You could also use one of the add-on config file readers which have more 
features, for example
http://voidspace.org.uk/python/modules.shtml#configobj

Another option is to make your config file be a Python module that you 
just import. What you wrote is pretty close to dictionary syntax. You 
could use this:
config = dict(
   apache = dict(
     process = '/usr/bin/httpd',
     # etc
   )
)

The syntax is not quite as user friendly but reading it is as easy as 
'import config'
