How can i fix json.decoder.JSONDecodeError ?

[JgKSuperstar]

If the json file is not empty, the yes code does not give an error

If start with empty file can not use json.load(file) on that file.
Make the the structure you want first with a dictionary,then json.dump to make it json file.
Example.

import json
from pprint import pprint

def write_json(new_date, filename='d.json'):
    json_make = {}
    with open(filename, 'r+') as file:
        json_make["emp_details"] = new_date
        file.seek(0)
        json.dump(json_make, file, indent=4)

if __name__ == '__main__':
    y = {
        "emp_name": "Nikhil",
        "email": "[email protected]",
        "job_profile": "Full Time",
    }
    write_json(y)

Output:
{
    "emp_details": {
        "emp_name": "Nikhil",
        "email": "[email protected]",
        "job_profile": "Full Time"
    }
}
