[Answer]-Iterate through a JSON field in django

Parse the JSON data with simplejson module:

from django.utils.simplejson import loads

data = {"access_token": "oauth_token_secret=XXXXXXXXXXXX&oauth_token=YYYYYYYYYYY", "7200": null, "id": null} tokens = parse_qs(loads(data)['access_token'])

json_dict = loads(data)
access_token = json_dict['access_token']

Then use what Jan suggested to you to parse the query string stored in access_token:

from urlparse import parse_qs

tokens = parse_qs(access_token)

print tokens['oauth_token_secret']
print tokens['oauth_token']

For parsing the access_token, you can use http://docs.python.org/library/urlparse.html#urlparse.parse_qs:

Parse a query string given as a string argument (data of type application/x-www-form-urlencoded). Data are returned as a dictionary. The dictionary keys are the unique query variable names and the values are lists of values for each name.
