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:

Answer 1

The correct answer depends on what you intend to do with the serialized version.

If you are going to unserialize back into Python, see Zero's answer.

If your serialized version is going to another language then you probably want to use an IntEnum instead, which is automatically serialized as the corresponding integer:

from enum import IntEnum
import json

class Status(IntEnum):
    success = 0
    failure = 1

json.dumps(Status.success)

and this returns:

'0'
