Thanks, i was thinking about something like that.

I try the staticmethod, it works fine. Very helpful.
But i don't like it very much, it seems 'complicated' (python was
supposed to be simple). I'll also try the dictionnary method.
My final idea was that a dictionnary would be perhaps simple in the
future to save/load as XML and a parser.
But perhaps i'm wrong with my vision of python.
On a more global perspective, what are the best method to implement a
simple config file with pyhton. Assuming i finally want to made a bundle
app for Mac, Windows and perhaps Linux.
I develop on Mac, and on this platform the config fil (preferences) have
to be stored in a special directory : ~/Library/Preferences, no problem.
But on other platform that's not the same directory and perhaps i would
also faced to permissions issues...
But first is there a way to determine on which platfrom the python
script is running ?
