json problem

[enigma619]

Hi

I'm new on this forum.
I'm working with json and python and i don't succeed to retrieve some information...

my json:

Output:
{
    "domaine": {
        "nom": {
            "service": ["test"]
        },
}

I'm trying to print only: "nom" but don't succeed in it.
My code:

with open('/tmp/file.json') as json_file1:
    data = json.load(json_file)

    for key, value in data.items():
        variable = data[domaine]

I only success to print only domaine, or all my json, not just "nom"

Sorry for this perhaps simply question..
Thanks for help

Alex
