How to read a specific value from within a JSON file? [duplicate]

I want to know how to read a specific objects value from within a JSON object.

    "worker_01": {
        "data": {
            "name": "Juan",
            "manager": 0,
            "weight": 75,
            "positions": {
                "FOH": 1,
                "MOH": 1,
                "BOH": 1
            }
        }
    },

I know previously in Node.js I could read them by doing *.get(worker_01.data.name)* but python doesn't really allow that. I want to know how do I do something similar to that in python.

Here is my source code.

import json as js

data_json = open('hello.json')
data_worker = js.load(data_json)

for i in data_worker['worker_01']:
    print(i)
1

Please, show valid JSON – buran
well, it is somewhat similar in Python really, something like data_worker['worker_01']['data']['name'], as a type data_worker here is a python dictionary if you use load, also a bit related: I would suggest using with to open files – Matiiss
Buran, i just copied a snipet of the JSON file, so it wasn't the correct format. Matiiss, thank you, this helped. works as i wanted it. – Carlos Gross
Once you have loaded the JSON, you work with the resulting structure of nested dictionaries and/or lists the exact same way that you would, if the data came from anywhere else. – Karl Knechtel

In Python, you can read JSON as a big python dictionary with mini listed dictionaries in between them all. With that in mind, you can index specific attributes from the JSON. For example based on your JSON, if a user wanted to get data on a persons name, you would do data_worker['worker_01']['data']['name'] to get the output 'Juan'
