Python provides no way to override how json.dumps serializes Infinity/-Infinity/NaN; if allow_nan is true, it encodes them as Infinity/-Infinity/NaN, in violation of the JSON spec and in violation of what JSON.parse accepts. If it's false, it throws a ValueError, Neither subclassing JSONEncoder nor passing a function in the |default| keyword argument overrides this. é)Úabsolute_import)Údivision)Úprint_functionNÚinfz-infúutf-8csÆt|tƒr|St|tƒrD|tkr$dS|tkr0dSt |¡r>dS|Sn~t|tƒrX| ˆ¡St|t t fƒrx‡fdd„|DƒSt|t ƒr˜‡fdd„t |ƒDƒSt|t ƒr¾t ‡fdd„| ¡Dƒ¡S|Sd S) aƒMakes Python object appropriate for JSON serialization. - Replaces instances of Infinity/-Infinity/NaN with strings. - Turns byte strings into unicode strings. - Turns sets into sorted lists. - Turns tuples into lists.
