python unable to access suds methods
===

I am trying to access the SOAP api using SUDS in python


    from suds.client import Client
    def initialize():
        url = 'http://uuuuuuuuuuuuuuu.com/wewewe/WsNBI?wsdl'
        username = 'xxxxx'
        password = 'ppppppp'
        client = Client(url)
        print client
        result = client.service.Login(nbiLogin NBILogin(username,password),)
        print result

i am unable to invoke the Login method, any idea how i can do this?

these are the methods returned by the query...
