ujson – JSON Encoding and Decoding

This module implements the corresponding CPython A subset of modules, as described below. Refers to CPython documents for details: json

This module allows conversion between Python objects and JSON data formats.

Function

ujson.dump(obj, stream)

Take obj serialize to JSON string, Write it to the given stream .

ujson.dumps(obj)

Convert dict type data to str，This function is required when writing data of type dict directly to JSON file, because an error will be reported. - obj Objects to convert

Example:

>>> obj = {1:2, 3:4, "a":6}
>>> print(type(obj), obj) #Originally of dict type
<class 'dict'> {3: 4, 1: 2, 'a': 6}
>>> jsObj = ujson.dumps(obj) #Convert dict type to str
>>> print(type(jsObj), jsObj)
<class 'str'> {3: 4, 1: 2, "a": 6}

ujson.load(stream)

Parsing given stream, interpret it as a JSON string and deserialize the data into Python objects. Returns the result object.

Parsing continues until the end of the file. If the data in the stream is not properly formed, then raise ValueError

ujson.loads(str)

Parse the JSON string and return the object. A valueerror exception will be thrown if the string is malformed.

Example:

>>> obj = {1:2, 3:4, "a":6}
>>> jsDumps = ujson.dumps(obj)
>>> jsLoads = ujson.loads(jsDumps)
>>> print(type(obj), obj)
<class 'dict'> {3: 4, 1: 2, 'a': 6}
>>> print(type(jsDumps), jsDumps)
<class 'str'> {3: 4, 1: 2, "a": 6}
>>> print(type(jsLoads), jsLoads)
<class 'dict'> {'a': 6, 1: 2, 3: 4}
