Either way, let me know by leaving a comment below.Īlso, try to solve the Python JSON Exercise to have a better understanding of Working with JSON Data in Python.Converts a Python dictionary or other native data type into a valid XML string. What do you think of this article? Or maybe I missed one of the ways to Convert JSON data Into a Custom Python Object. Output Converting JSON into Python Object Print(studentObj.rollNumber, studentObj.name) Print("Object type is: ", type(studentObj)) Print("Converting JSON into Python Object") StudentJson = json.dumps(student, cls=StudentEncoder, indent=4) import jsonĭef _init_(self, rollNumber, name, *args, **kwargs): i.e., we can map the dict object to a custom object. we can construct a new custom object by passing the dict object as a parameter to the Student Object constructor. StudentJsonData = 'ĭecode JSON formatted Data using jsonpickleġ Emma 82 74 Create a new Object, and pass the result dictionary as a map to convert JSON data into a custom Python ObjectĪs we know json.loads() and json.load() method returns a dict object. Return namedtuple('X', studentDict.keys())(*studentDict.values())
In this example, we are converting Student JSON data into a custom Student Class type. Let’ see the simple example first then we can move to the practical example. In this case, we can access the elements using keys and indexes.
Like the dictionary type objects, it contains keys and that are mapped to some values. The namedtuple is class, under the collections module. so we can get custom type at the time of decoding JSON. and pass this newly created function to an object_hook parameter of a json.loads method. To convert JSON into a custom Python type we need to follow the following:Īs we know json.load() and json.loads() method convert JSON into a dict object so we need to create a custom function where we can convert dict into a custom Python type. Using this feature, we can implement custom decoders. So when we execute json.loads(), The return value of object_hook will be used instead of the dict. The object_hook is an optional function that will be called with the result of any object literal decoded (a dict). We can use the object_hookparameter of the json.loads() and json.load() method.
