Why is my Python `json.load()` function failing, and how can I fix the invalid JSON syntax?

Understanding JSON Parsing Failure in Python

This question arises when attempting to parse JSON data using the json.load() function but encountering an error. The JSON data provided in the file appears invalid, which prevents Python from parsing it correctly.

The Issue: Invalid JSON Syntax

The JSON data supplied contains two elements, "masks" and "parameters," that are defined incorrectly. In JSON, arrays are expressed using square brackets ([]), while objects are defined using curly braces ({}). However, the problematic elements are constructed using both notations, resulting in invalid syntax.

Valid JSON Syntax

The correct JSON structure for these elements would be:

...
"masks": {
    "id": "valore"
},
"parameters": {
    "id": "valore"
}
...

Resolving the Issue

To resolve this issue, rectify the JSON syntax by modifying the file to match the above structure. Use curly braces for both "masks" and "parameters" objects. Once the JSON data is in valid format, the json.load() function should successfully parse it, allowing you to access the data as needed.

Extracting Values from Parsed JSON

Once the data is successfully parsed, you can retrieve values using Python's dictionary syntax. For instance, to access the "id" key within the first "map" object:

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

Similarly, you can obtain values from the "masks," "om_points," and "parameters" elements using the appropriate key references.
