May use simple file in known place:
$HOME/.myprefs
$HOME/.conf/myprefs

Or host specific configuration API:
WindowsRegistry HKEY_CURRENT_USER\Software\MySociety\MyApp\myprefs


See os.getenv, and _winreg Windows specific module.
See also standard ConfigParser module
Hope you know how to read/write files.
