How to fix sorting in JSON?

Question

Python

When I change the JSON file and save it, it is sorted alphabetically, which is not usual for me.
JSON

{
   "a": {
        "a": "a",
        "g": "g",
        "b": "b"
    }
}

After saving:

{
   "a": {
        "a": "asasas",
        "b": "b",
        "g": "g"
    }
}

I save like this

with open("file.json") as f:
    a = json.load(f)

with open("file.json", "w") as f:
    a["a"]["a"] = "asasas"
    json.dump(info, f, indent=2, ensure_ascii=False)

How to fix it?

Answer 1

Firstly, before Python 3.7, there was no concept of the order of keys in the dictionary (I myself was surprised when I found out).
Secondly, there is a parameter in the documentation:
json.dump(... ,sort_keys=False)

Answer 2

There is no way to fix it, the json format does not guarantee that the order of the keys will be preserved.
