Python – ImportError: cannot import name. Can’t figure out why

Your data is not valid JSON format. You have [] when you should have {}:

• [] are for JSON arrays, which are called list in Python
• {} are for JSON objects, which are called dict in Python

Here's how your JSON file should look:

{
    "maps": [
        {
            "id": "blabla",
            "iscategorical": "0"
        },
        {
            "id": "blabla",
            "iscategorical": "0"
        }
    ],
    "masks": {
        "id": "valore"
    },
    "om_points": "value",
    "parameters": {
        "id": "valore"
    }
}

Then you can use your code:

import json
from pprint import pprint

with open('data.json') as f:
    data = json.load(f)

pprint(data)

With data, you can now also find values like so:

data["maps"][0]["id"]
data["masks"]["id"]
data["om_points"]

Try those out and see if it starts to make sense.

@Hugo was right in that it was a settings.py problem. But I didn't had that problem when running through the Django environment. But when I wanted to run unit tests one by one (By using Pydev's run as unittest) it failed to run. What I needed to do was to add the Django settings module information, so for now what I'm doing is adding the following lines to my unit tests:

from django.core import management;
import BookIt.settings as settings;
management.setup_environ(settings)

This loads my Django project settings and allow me to run as regular unittest. If anyone has better suggestion on how to configure this more cleanly in Pydev please let me know.
