Serialising an Enum member to JSON

Question

How do I serialise a Python Enum member to JSON, so that I can deserialise the resulting JSON back into a Python object?

For example, this code:

If you are using jsonpickle the easiest way should look as below.

from enum import Enum
import jsonpickle


@jsonpickle.handlers.register(Enum, base=True)
class EnumHandler(jsonpickle.handlers.BaseHandler):

    def flatten(self, obj, data):
        return obj.value  # Convert to json friendly format


if __name__ == '__main__':
    class Status(Enum):
        success = 0
        error = 1

    class SimpleClass:
        pass

    simple_class = SimpleClass()
    simple_class.status = Status.success

    json = jsonpickle.encode(simple_class, unpicklable=False)
    print(json)

After Json serialization you will have as expected {"status": 0} instead of

{"status": {"__objclass__": {"py/type": "__main__.Status"}, "_name_": "success", "_value_": 0}}
