[Python-ideas] Re: JSON Serializing UUID objects

I published a lib on PyPi that does that, which pushed to write a complete readme, that I will reproduce here if anybody is interested in more discussion about this, along with my conclusions: Overall, it seems like the cost of maintenance is going to be insignificant. While the value is reduced

Or, there might be a way to get the best of both worlds. Consider this silly example: encoded = yourobject.__jsondump__() # this should work yourobject == YourClass.__jsonload__(encoded) Basically very similar to __getstate__ and __setstate__ with pickle, with the following

[Python-ideas] Re: JSON Serializing UUID objects

Since there's no standard for this in json, deciding to serialize to str is quite arbitrary. I personally serialize UUIDs to binary data as it takes less space. Some serialize it to hexadecimal. Tbh, it sounds like a good idea but can have it's pitfalls. On Wed, Jun 10, 2020, 4:43 PM J. Pic

[Python-ideas] Re: JSON Serializing UUID objects

Good point, but then I'm not sure the decoder could be used for untrusted json anymore. Another solution would be to generate a schema in a separate variable, which would represent the JSON structure with Python types. Also, there's still simple regexp pattern matching that could also be good

[Python-ideas] Re: JSON Serializing UUID objects

I understand, do you think the python standard library should provide a JSONEncoder and JSONDecoder that supports python standard library objects ? It would be optional to use, but if you use it then any object from the python standard library will just work.

[Python-ideas] Re: JSON Serializing UUID objects

I don't know how or even whether this would be possible ootb. On one side, I do really like the idea; on the other hand, it kind of seems like going down a bumpy road (as you said, datetimes? filepaths?urls?). And the de-serialization would not be easy. What if we added a function call for the
