python连接Oracle数据库的代码，需要引用cx_Oracle库

#coding=UTF-8      import cx_Oracle      def hello():          '''Hello cx_Oracle示例：          1)打印数据库版本信息.          2)查询表数据.'''          conn = cx_Oracle.connect("obs61","obs61","tx8i.hp")          cur = conn.cursor()          try:              print "Oracle Version:%s" % conn.version              print "Table SUB_POLICY rows:"              cur.execute('select * from wlan_future_event')              for row in cur:                  print row          finally:              cur.close()              conn.close()      hello()
