Python 2.7 json compare1/27/2024 ![]() Object_hook, if specified, will be called with the result of every JSON It also understands NaN, Infinity, and -Infinity as theirĬorresponding float values, which is outside the JSON spec. Performs the following translations in decoding by default: JSON JSONDecoder ( *, object_hook=None, parse_float=None, parse_int=None, parse_constant=None, strict=True, object_pairs_hook=None ) Object_hook is also defined, the object_pairs_hook takes priority.ġ9.2.2. Rely on the order that the key and value pairs are decoded (for example,Ĭollections.OrderedDict() will remember the order of insertion). This feature can be used to implement custom decoders that Return value of object_pairs_hook will be used instead of theĭict. Result of any object literal decoded with an ordered list of pairs.

Keys in key/value pairs of JSON are always of the type str. That string is used to indent each level. Of 0, negative, or "" will only insert newlines. Object members will be pretty-printed with that indent level. If indent is a non-negative integer or string, then JSON array elements and If allow_nan is true, their JavaScript equivalents ( NaN, Inf, -inf) in strict compliance of the JSON specification.
