Question

I’ve got some json from last.fm’s api which I’ve serialised into a dictionary using simplejson. A quick example of the basic structure is below.

{
  "artist": "similar": {
    "artist": {
      "name": "Blah",
      "image": [{
        "#text": "URLHERE",
        "size": "small"
      }, {
        "#text": "URLHERE",
        "size": "medium"
      }, {
        "#text": "URLHERE",
        "size": "large"
      }]
    }
  }
}

Any ideas how I can access the image urls of various different sizes?

Thanks,
Jack

Answer 1

Python does not have any problem with # in strings used as dict keys.

>>> import json
>>> j = '{"#foo": 6}'
>>> print json.loads(j)
{u'#foo': 6}
>>> print json.loads(j)[u'#foo']
6
>>> print json.loads(j)['#foo']
6

There are, however, problems with the JSON you post. For one, it isn’t valid (perhaps you’re missing a couple commas?). For two, you have a JSON object with the same key “image” three times, which cannot coexist and do anything useful.
