How to Parse values from a JSON file

Question

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?

Answer 1

import json
from pprint import pprint

with open('data.json') as f:
    data = json.load(f)

pprint(data)

With data, you can now also find values like so:

data["maps"][0]["id"]
data["masks"]["id"]
data["om_points"]
