I want to change the values in a json file. The json file contents are commented out. I want to change the values individually with having to write to the file separately for each value.

import json

"""
{
    "keys": {
        "developer": {},
        "personal": {
            "api_key": "1234567890",
            "client_id": "9876543210",
            "client_secret": "ncjegcbcncwkwdcowdch"
        }
    }
}
"""

json_file = "/home/api_keys.json"

with open(json_file) as json_data:
    data = json.load(json_data)

with open(json_file, "w") as jsonFile:
    json.dump(data, jsonFile)

    data["keys"]["personal"]["api_key"] = "9999"

with open(json_file, "w") as jsonFile:
    json.dump(data, jsonFile)   

    data["keys"]["personal"]["client_id"] = "000000000000"

    data["keys"]["personal"]["client_secret"] = "hyfgdjocoduxbxlwowichcnckw"

with open(json_file) as json_data:
    data = json.load(json_data)

    api_key = data["keys"]["personal"]["api_key"]
    client_id = data["keys"]["personal"]["client_id"]
    client_secret = data["keys"]["personal"]["client_secret"]
