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()

If the example code you posted mirrors your real code, there really isn't any reason for the properties at all. You could just do:

class User(object):
    def __init__(self):
        self.name = None
        self.age = None

since you're not really hiding anything from the user behind the underscores and properties anyway.

If you do need to do the transformation, I like to do it in a custom encoder:

class MyEncoder(json.JSONEncoder):
    def default(self, o):
        return {k.lstrip('_'): v for k, v in vars(o).items()}

json_encoded_user = json.dumps(some_user, cls=MyEncoder)
