when i serialize and deserialize python built-in structure I'm expect output same as input
arr2 = [1,2,'3']
arr2_json = json.dumps(arr2)
json.loads(arr2_json)
Out[16]: [1, 2, '3']
BUT when I'm tring do it with dict I got str keys instead of integer
dict1 = {0: 'object0', '1': 'object2'}
json1 = json.dumps(dict1)
json.loads(json1)
Out[6]: {'0': 'object0', '1': 'object2'}
Notice keys must be [0, '1'] but actually are ['0', '1']

See the documentation. This is documented behavior. The JSON format supports only string keys, and all keys are coerced to strings when serialized to JSON. |
