I found this result when searching for 'omniorbpy "out parameter"':
http://www.omniorb-support.com/pipermail/omniorb-list/2000-April/015244.html
I don't know for certain that this is the way omniorbpy behaves today,
but it is a very pythonic way to work.

| Out arguments in the Python mapping appear as extra return values in a
| tuple. So, if you have IDL
|
| interface I {
| long op(in string a, out short b, inout double c);
| };
|
| Then to call op, you do
|
| (result, b, c) = i.op(a, c)
|
| I recommend that you read the mapping specification, which you can
| download from
|
