用python去调用webservice时纠结了大半天，老是报错，求帮忙指导一下?报错

今天使用python去调用webservice时纠结了大半天，老是报错，求帮忙指导一下

源码如下：

from suds.client import Client 

def webservice(): #     

    u"""创建WebService请求"""   

    url = 'http://.....此处省略.asmx' 

    client = Client(url) 

 result = client.service 

    return result 

websev = webservice() 

ws = websev.SendBatchMASBySoap()

报错信息如下：
