Test 200 code in python/django

I'm trying to test my project and I want to get a 200 status code with the following test:

import requests

def test_200(self):

    url_csrftoken = 'http://ift.tt/1m0n8Yg'
    url = 'http://127.0.0.1:8000/'
    url_login = 'http://ift.tt/2d7U5H9'
    client = requests.session()
    client.get(url_csrftoken)
    csrftoken = client.cookies['csrftoken']
    login_data = dict(inputUser='admin', inputPassword='mypass', csrfmiddlewaretoken=csrftoken, next=url)
    client.post(url_login, data=login_data)
    r = client.get(url)
    self.assertEqual(r.status_code,200)

It stops at: client.get(url_csrftoken) and gives the following error:

Traceback (most recent call last):
  File "tests2.py", line 115, in test_networking
    csrftoken = client.cookies['csrftoken']
