If you want to iterate over both keys and values of the dictionary, do this:

for key, value in data.items():
    print(key, value)

UPDATE

With Python3, you can do it in one line, using SimpleNamespace and object_hook:

import json
from types import SimpleNamespace

data = '{"name": "John Smith", "hometown": {"name": "New York", "id": 123}}'

# Parse JSON into an object with attributes corresponding to dict keys.
x = json.loads(data, object_hook=lambda d: SimpleNamespace(**d))
# Or, in Python 3.13+:
#   json.loads(data, object_hook=SimpleNamespace)
print(x.name, x.hometown.name, x.hometown.id)

OLD ANSWER (Python2)

In Python2, you can do it in one line, using namedtuple and object_hook (but it's very slow with many nested objects):

import json
from collections import namedtuple

data = '{"name": "John Smith", "hometown": {"name": "New York", "id": 123}}'

# Parse JSON into an object with attributes corresponding to dict keys.
x = json.loads(data, object_hook=lambda d: namedtuple('X', d.keys())(*d.values()))
print x.name, x.hometown.name, x.hometown.id

or, to reuse this easily:

def _json_object_hook(d): return namedtuple('X', d.keys())(*d.values())
def json2obj(data): return json.loads(data, object_hook=_json_object_hook)

x = json2obj(data)

If you want it to handle keys that aren't good attribute names, check out namedtuple's rename parameter.

Use json.loads it will convert the json string to a dict containing dicts, list, etc.

Edit 2: You can access each item like this: json_object['scans']['TotalDefense']['version'] contd. But you may also need to json.loads(json.load(response)) as I mentioned in my comment below.

Edit 1: In your example, we should not be seeing "scans" again for print json_object['scans'].

From http://docs.python.org/library/json.html:

>>> import json
>>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]')
[u'foo', {u'bar': [u'baz', None, 1.0, 2]}]

That page also has info on how to do more complex decoding.

import json
weather = urllib2.urlopen('url')
wjson = weather.read()
wjdata = json.loads(wjson)
print wjdata['data']['current_condition'][0]['temp_C']

What you get from the url is a json string. And your can't parse it with index directly. You should convert it to a dict by json.loads and then you can parse it with index.

Instead of using .read() to intermediately save it to memory and then read it to json, allow json to load it directly from the file:

wjdata = json.load(urllib2.urlopen('url'))

Very simple:

import json
data = json.loads('{"one" : "1", "two" : "2", "three" : "3"}')
print(data['two'])  # or `print data['two']` in Python 2
