Python Deep Destruction Like JavaScript and assingment to new Object

Question

let newJson = {};

({
    "foo": {
        "name": newJson.FirstName,
        "height": newJson.RealHeight
    }
} =

{
    "foo": {
        "name": "Felipe",
        "height": "55"
    }
});
console.log({newJson})

As we Know the above code will return in JS the follow output:

{newJson :{FirstName: "Felipe", RealHeight: "55"}}

I Would like to kwnow if there is a Lib or a way to do it in PYTHON

Look at the `json` standard library. Find the docs [here](https://docs.python.org/3/library/json.html) — Edo Akse, Jun 16 '21 at 21:27

Searching for "desctructured assignment in Python" yields results.

You can use the native "tuple unpacking" as defined in PEP 448 :

json_data = {
    "foo": {
        "name": "Felipe",
        "height": "55"
    }
}

first_name, real_height = json_data["foo"]["name"], json_data["foo"]["height"]

print(first_name, real_height)
# Felipe 55

Or you can use something a bit closer which is based on the Python Data Model (inspired from this answer) :

from operator import itemgetter

json_data = {
    "foo": {
        "name": "Felipe",
        "height": "55"
    }
}

first_name, real_height = itemgetter("name", "height")(json_data["foo"])

print(first_name, real_height)
# Felipe 55

What I need is something that could be deep, tuple unpacking i know but not enouth — Felipe Augusto Gonalves Basili, Jun 22 '21 at 12:32
@FelipeAugustoGonalvesBasili Python does **not** permit it with the current parser. — Lenormju, Jun 22 '21 at 15:20
