Hello and thank you,

To be honnest I must take a moment and translate your example into french to 
really understand it (but I believe it's very well explained :) and I will 
understand)
I remember at school when an unix teacher was explaining what was an UID and 
a GID, like if the files were two persons talking and asking each other " 
what's your UID?, we got the same, so, what is your GID ?", and I never had 
problems with UID and GID since that :D

I have thinked to try to return an array of values  like a function does 
(instead of passing many params to a sub) but didn't take the time to do it.

I believe that programming in python involves to learn a kind of new 
phillosophy, new words too. as an exemple of this, for me
a 'tuple' is related to database stuff. What I call an array seems to be 
called a list in python (C programmers use the word 'matrix' when talking of 
a two dimentionnal array, and 'vector' when talking of a one dimention 
array...sorry, a list :D ).

Dominique.
