I've read this, but I thought that this tuple is returned with the
return statement. I am new to python and I never seen such
a constract:

I have had only the IDL  and the py File from the IDL,
were stand take *args and return the return value.
In none of my python books such a construct is described. I'm sorry.

Thanks for helping me,
