python - Why json.keys() get keys in different order -

-

this question has answer here:

hi have following code in python:

import json jsonpost = json.loads('{"player": {"_id": "3","firstname":"kim","surname":"jones"},"newtable": {"_id": "4","surname": "abcd"}}')  key in jsonpost.keys():     innerkey in jsonpost[key]:         print innerkey

my question why when print out inner key order of keys jsonpost['player'] following:

_id , surname, firstname

python dictionaries implemented internally hash table. means key order not preserved. issue?
