How to convert Object with Properties to JSON without “_” in Python 3?

Question

I would like to convert an Python object into JSON-format.

The private attributes of the class User are defined using properties. The method to_Json()

Answer 1

I had a similar problem, but I had private fields with two underscore characters.

class User:
    def __init__(self, id, name):
        self.id = id
        self.name = name

    @property
    def id(self):
        return self.__id

    @id.setter
    def id(self, id):
        self.__id = id

    @property
    def name(self):
        return self.__name

    @name.setter
    def name(self, name):
        self.__name = name

Therefore, my json encoder is slightly different

from json import JSONEncoder


def beautify_key(str):
    index = str.index('__')
    if index <= 0:
        return str

    return str[index + 2:]


class JsonEncoder(JSONEncoder):

    def default(self, o):
        return {beautify_key(k): v for k, v in vars(o).items()}
