Hi all, This is a proposal to enable uuid objects serialization / deserialization by the json module out of the box. UUID objects cast to string:
example = uuid.uuid4() str(example) 'b8bcbfaa-d54f-4f33-9d7e-c91e38bb1b63'
The can be casted from string:
example == uuid.UUID(str(example)) True
But are not serializable out of the box:
json.dumps(example) Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.8/json/__init__.py", line 231, in dumps return _default_encoder.encode(obj) File "/usr/lib/python3.8/json/encoder.py", line 199, in encode chunks = self.iterencode(o, _one_shot=True) File "/usr/lib/python3.8/json/encoder.py", line 257, in iterencode return _iterencode(o, 0) File "/usr/lib/python3.8/json/encoder.py", line 179, in default raise TypeError(f'Object of type {o.__class__.__name__} ' TypeError: Object of type UUID is not JSON serializable
Wouldn't it be pythonically possible to make this work out of the box, without going through the string typecasting ? If that discussion goes well perhaps we can also talk about datetimes ... I know there's nothing about datetime formats in the json specification, that users are free to choose, but could we choose a standard format by default that would just work for people who don't care about the format they want. Thank you in advance for your replies Have a great day -- ∞
