@Luca: you might want to open a new feature request issue; it's not clear to me what exact behaviour change you're proposing for Python. What was rejected in this issue was the proposal to *automatically* convert NaNs and infinities to nulls by default, but that still leaves open the possibility of adding an option to do such conversion, provided that a sufficiently strong case could be made for adding such an option, and that we can figure out what we want the behaviour should be (should _all_ things that JSON doesn't know how to encode be converted to null, or just infinities and nans?) If you want standards compliance, then that's already there: you can use the existing flag allow_nan=False when generating JSON. I agree that it would have been better if that were the default, but changing it now is probably a no-go - it would break too much existing code. I'm still confused by Arjan Staring's comments: they seem to be saying that the JSON specification states that a NaN should be converted to the string "null", but there's nothing in RFC 7159 to support that - as you point out, it explicitly says that NaNs and infinities are disallowed. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40633> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
