I don't think you can with plPython at least not without reformatting
the list within the function itself.

You would actually have to have a set. What I believe you are trying to
do is transform a list to a result set. I don't think you can do that
without some additional programming within the function.
Somebody may know of a better way but what I would think would happen is
this:
Break up list, insert each value of list into a temp table as a row,
return set of temp table.
