Iterable JSON in Python

Posted on 2016-11-17 00:00:00 by Chris

Python works relly nicely with JSON objects so long as all of your keys are nicely labeled and you dont have object or arrays with no key labels!

json = {
          "key" : "value",
          "anotherkey" : "value"
        }

You can access the items really easily:

data = json.loads(json);

But it seems to work much less well, or at least, much less obviously if you have a JSON array of objects:

json = {
          "key": "value",
          {
            "a1key1" : "value",
            "a1key1" : "value"
          },
          {
            "a2key1" : "value",
            "a2key1" : "value"
          },
          {
            "a3key1" : "value",
            "a3key1" : "value"
          }
        }

To access objects easily within your program, I have found it easiest if you add an additonal step to convert you JSON into a regular python array:

data = json.loads(json)
        data = {int(k):v for k,v in data.items() if k.isdigit()}
