Parse json output directly from a subprocess output

I can't figure out how parse json output directly from a subprocess output.

code snippet

cmd = ['./mmdbinspect', '--db', '/usr/local/var/GeoIP/GeoLite2-City.mmdb', ip]
        # result returns json
        result = subprocess.run(cmd, stdout=subprocess.PIPE)
        result = json.loads(result)
        # parse & print
        print(result[0]['Lookup'])
        print(result[0]['Records'][0]['Record']['country']['iso_code'])
        print(result[0]['Records'][0]['Record']['country']['names']['en'])

If I write result to file, then perform json.load it works as expected but I would like to combine and skip that step.

Traceback error

TypeError: the JSON object must be str, bytes or bytearray, not CompletedProcess

From the docs The returned instance will have attributes args, returncode, stdout and stderr. To use it, load the json string from stdout.

result = json.loads(result.stdout)

this should work

    result = json.load(result.read())
