Accessing API using Python -

i trying retrieve data api , receiving

'set' object has no attribute 'items'

this api.py , have import views

import json import urllib import urllib2 import pycurl  def get_resources(request, filter, endpoint, lookup):     headers = {'x-auth-token:%s' % request.user.token, 'content-type:application/json'}     data = urllib.urlencode(filter)     url = endpoint+lookup     req = urllib2.request(url, data, headers)     response = urllib2.urlopen(req)     result = json.loads(response.read())     return result 

and views.py this

def indexview(request):     resources = json.dumps(get_resources(request,{}, api_endpoint, '/v2/meters'))     return httpresponse(resources, mimetype='application/json') 

i know doing wrong here, hope me thanks.

the line:

headers = {'x-auth-token:%s' % request.user.token,            'content-type:application/json'} 

defines set. , should dictionary (which has : somewhere in after follows value key before :)
