JSON output sorting in Python

I've a problem with JSON in python. In fact, if I try to execute this code, python gives me a sorted JSON string! For example: values = { 'profile': 'testprofile', 'format': 'RSA_RC4_Sealed', 'enc_key': base64.b64encode(chiave_da_inviare), 'request': base64.b64encode(data) } values_json = json.dumps(values, sort_keys = False, separators = (',', ':')) And this is the output: { "profile": "testprofile", "enc_key": "GBWo[...]NV6w==", "request": "TFl[...]uYw==", "format": "RSA_RC4_Sealed" } As you can see, I tried to use "sort_keys=False" but nothing changed. How can I stop Python sorting my JSON strings?
You are storing your values into a Python dict which has no inherent notion of ordering at all, it's just a key-to-value map. So your items lose all ordering when you place them into the values variable. In fact the only way to get a deterministic ordering would be to use sort_keys=True, which I assume places them in alphanumeric ordering. Why is the order so important?
