I'm trying to parse a JSON correctly with Python/Django

I'm trying to consume some data from a JSON with requests, but I consistently receive a Parsing error when I try to validate.

I try this code, transforming from dict to string, and later to JSON.

import requests
import json

r = requests.get('http://codehere.com', auth=('user', 'pass')).json()
json.loads(json.dumps(r))
print(r)

Before:

Expected: A valid JSON. I don't know if there are more steps, I'm trying to use that code on Django. Its shows only a complete string.
