Parsing JSON and storing data in a Python class

This is my JSON data.

[
    {
        "id":1,
        "name":"abc",
        "phone": "12345",
        "Charecteristics": [
            {
                "id":1,
                "name":"Good Looking",
                "rating": "Average",
            }
            {
                "id":2,
                "name":"Smart",
                "rating": "Excellent",
            }
        ]
    },
    { ... },
    { ... }
]

I have two classes in Python

class Character(object):
    id = 0
    name = ""
    rating = ""

class Person(object):
    id = 0
    name = ""
    phone = ""
    Characteristics = []

I need to parse the JSON data and create the corresponding classes. Classes require no explanation: for example, a person has an array of character classes.

How to create and store data properly?

Also, how can I access specific Person data? that is, the data and characteristics of a person.

Take a look at colander ; it turns a JSON data structure into Python objects without difficulty.

You define a schema:

import colander


class Characteristic(colander.MappingSchema):
    id = colander.SchemaNode(colander.Int(),
                             validator=colander.Range(0, 9999))
    name = colander.SchemaNode(colander.String())
    rating = colander.SchemaNode(colander.String())        


class Characteristics(colander.SequenceSchema):
    characteristic = Characteristic()


class Person(colander.MappingSchema):
    id = colander.SchemaNode(colander.Int(),
                             validator=colander.Range(0, 9999))
    name = colander.SchemaNode(colander.String())
    phone = colander.SchemaNode(colander.String())
    characteristics = Characteristics()


class Data(colander.SequenceSchema):
    person = Person()

then go to the JSON data structure using the following:

deserialized = Data.deserialize(json.loads(json_string))
