我现在在用python调用oracle的一个接口，但是返回值是一个游标，请问我该如何获取这个游标的具体值啊create or replace package testpackage as
type test_cursor is ref cursor;
end testpackage;
/

create or replace procedure sp_pro3(spdeptno in number,sp_cursor out testpackage.test_cursor)
is
begin
  open sp_cursor for select * from emp where deptno=spdeptno;
end;
/

In [58]: import cx_Oracle as cx

    ...: conn = cx.connect('scott/123456@MissWang/orcl')

    ...: cursor = conn.cursor()

    ...: spdeptno = 10

    ...: sp_cursor = cursor.var(cx.CURSOR)

    ...: cursor.callproc('sp_pro3',[spdeptno,sp_cursor])

Out[58]: [10, <cx_Oracle.Cursor on <cx_Oracle.Connection to scott@MissWang/orcl>>]

请问我该如何获取这个游标的具体值啊
