Python - PL/SQL - Pass VARRAY - return cursor

[hencre]

hi,

Im calling Oracle 10g stored proc from python 2.6.
1. How do I pass String VArray (list in python) to stored proc ?
2. How do I return cursor from Oracle stored proc ?
3. How do I return list of strings from Oracle stored proc ?

My Oracle SP looks like >>

create or replace PROCEDURE TLMDEV.TESTALL
( traderNames IN EVTX_STRING_ARRAY, resultSet OUT EVTX_CURSOR_TYPE.cursorType
) AS
BEGIN
  open resultSet for [some sql];
END TESTALL;

Thanks in advance.
