Python using HTTP for request

#requests is a python module used for Posting HTTP requests.
#module can be downloaded from https://pypi.python.org/pypi/requests
#Getting the input xml file as argument and post the xml contents in the INPUT_DATA attribute
import requests,codecs,sys,pprint
url = 'http://localhost:8080/api/cmdb/ci/'
fileName = sys.argv[1]
xmlcontent = open(fileName, 'r').read()
args = {'OPERATION_NAME':'add','TECHNICIAN_KEY':'398DA976-0242-47AF-BE43-F6377AEC3EBA','format':'xml','INPUT_DATA':xmlcontent}
response = requests.post(url,params=args)
print response.text
