Soap call in Python

Question

I tried to call a soap service. My call is success but its returns empty value.Below i attached my soap request and response schema. Its takes 1d array as input and return that array.

Request Schema

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <CalculateWeb1D xmlns="http://tempuri.org/">
      <HCID>string</HCID>
      <jaggedobjDataMICRO>
        <string>string</string>
        <string>string</string>
      </jaggedobjDataMICRO>
      <numeratorID>int</numeratorID>
    </CalculateWeb1D>
  </soap:Body>
</soap:Envelope>

Response Schema

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <CalculateWeb1DResponse xmlns="http://tempuri.org/">
      <CalculateWeb1DResult>
        <string>string</string>
        <string>string</string>
      </CalculateWeb1DResult>
    </CalculateWeb1DResponse>
  </soap:Body>
</soap:Envelope>

My code to call soap service

from SOAPpy import WSDL

import warnings
warnings.simplefilter('ignore',DeprecationWarning)
import SOAPpy

wsdlFile = 'http://204.9.76.243/nuCast.DataFeedService/Service1.asmx?WSDL'
server = WSDL.Proxy(wsdlFile)
server.soapproxy.config.dumpSOAPOut = 1
server.soapproxy.config.dumpSOAPIn = 1
print server.CalculateWeb1D(str(1073757),[1,2],99)

and my output

Here's a working version that uses suds client:

#!/usr/bin/env python
from suds.xsd.doctor import Import, ImportDoctor
from suds.client import Client

# enable logging to see transmitted XML
import logging
logging.basicConfig(level=logging.INFO)
logging.getLogger('suds.client').setLevel(logging.DEBUG)

# fix broken wsdl
# add <s:import namespace="http://www.w3.org/2001/XMLSchema"/> to the wsdl
imp = Import('http://www.w3.org/2001/XMLSchema',
             location='http://www.w3.org/2001/XMLSchema.xsd')
imp.filter.add('http://tempuri.org/')
wsdl_url = 'http://204.9.76.243/nuCast.DataFeedService/Service1.asmx?WSDL'
client = Client(wsdl_url, doctor=ImportDoctor(imp))

# make request
arrayofstring = client.factory.create('ArrayOfString')
arrayofstring.string = [1,2]
print client.service.CalculateWeb1D(1073757, arrayofstring, 99).string
