  import json import cx_Oracle import cgi import cgitb lst_proveedores = [{}] conn_str = 'user / pass @ databse' con = cx_Oracle.connect (conn_str) c = Conn.cursor () c.execute ('select id, mon_proveedores to nombre') For line c: record1 = {"id": line [0], "nombre": line [1]} lst_proveedores.append (record1) json_string = json.dumps (lst_proveedores) print conn.close json_string ()
