"urllib.request" library using the bellow code.

nothing...

With same data When I test using C# it working fine.. Response

But I am using below python code i am getting response only "<HTML></
HTML>".

Is there any in my code..

 req  = urllib2.Request(url) // url is valid url
 req.add_header('Authorization','AuthSub token="xxxxxxxxxxxxx"')
 req.add_header('Content-Type','application/atom+xml')
 req.data=data  // data is having valid xml data
 r = urllib2.urlopen(req)

print(r.code) // output 200
print(r.msg) // output OK
print(r.read()) //<HTML></HTML>
