Hi Duncan,
You are right, I should have put the entire code but my question was
more theroretical and I know that the code that I posted won't work.

Let me simplified my question, I need to be able to write to the same
log file from different classes. and even more, from different
threads.
Is there any existing python Log object that do so? I no, I created my
own Log object that only open file and write a line to it, how can I
make it be global? Should I use it as a static object? will it work?
(offcurse in the case of the threads I'll use utex)

Thanks again,
DaveD
