I have this JSON in a file:
{
    "maps": [
        {
            "id": "helloworld",
            "iscategorical": "0"
        },
        {
            "id": "helloworld",
            "iscategorical": "0"
        }
    ],
    "masks": [
        "id": "valuerr"
    ],
    "om_points": "value",
    "parameters": [
        "id": "valuerr"
    ]
}
I wrote this script which prints all of the json text:
json_data=open(file_directory).read()
data = json.loads(json_data)
pprint(data)
How can I parse the file and extract single values?
