Why is my Python JSON parser throwing an 'Expecting ',' delimiter' error?

Why can't Python parse this JSON data?

You're trying to parse a JSON file into Python using the json.load() function, but you're getting an error message saying "Expecting ',' delimiter." This is because the JSON data you're trying to parse is not valid.

Specifically, you have a syntax error in the "masks" and "parameters" elements. These elements are not valid JSON objects, because they are not enclosed in braces ({}). Instead, they are enclosed in square brackets ([]), which are used for JSON arrays.

To fix this error, you need to change the square brackets to braces in the "masks" and "parameters" elements. The correct JSON data should look like this:

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

Once you've fixed the JSON data, you should be able to parse it into Python using the json.load() function without any errors. You can then use the data variable to access the values in the JSON data. For example, you can get the value of the "id" field in the first map using the following code:

data["maps"][0]["id"]
