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 ).
