Build a JSON Object in Python
Below are some of the ways by which we can build a JSON object in Python:
- Using Python Dictionary
- Using json.loads( )
- Using json.JSONEncoder
Build a JSON Object Using Python Dictionary
JSON module is imported to deal with JSON objects. A Python dictionary named ‘data’ is used to store the object in key-value pairs. json.dumps( ) is used convert the Python dictionary into JSON formatted string and result is displayed.
Python3
import json data = { "name" : "Guru" , "age" : 19 , "isStudent" : True } json_string = json.dumps(data) print ( type (json_string)) print (json_string) |
<class 'str'> {"name": "Guru", "age": 19, "isStudent": true}
Build a JSON Object Using json.loads( ):
In this example, the json.loads()
function is used to parse a JSON-formatted string json_string
into a Python dictionary named data
. The resulting dictionary is then printed, representing the decoded JSON data.
Python3
import json json_string = '{"name": "GFG", "age": 19, "isStudent": true}' data = json.loads(json_string) print ( type (json_string)) print (data) |
<class 'str'> {'name': 'GFG', 'age': 19, 'isStudent': True}
Build a JSON Object Using json.JSONEncoder:
Encoder function is defined that’s used for encoding sets and converting to list. A json object named ‘gfg’ is created as a set. This list is converted into a dictionary named ‘json_data’. The dictionary is converted into o a JSON string json_string using json.dumps() with the custom encoder ‘Encoder’.
Python3
import json def encoder(obj): if isinstance (obj, set ): return list (obj) return obj gfg = [( 'name' , 'Hustlers' ), ( 'age' , 19 ), ( 'is_student' , True )] json_data = dict (gfg) json_string = json.dumps(json_data, default = encoder) print ( type (json_string)) print (json_string) |
<class 'str'> {"name": "Hustlers", "age": 19, "is_student": true}
Build a Json Object in Python
JSON (JavaScript Object Notation) is a lightweight data-interchange format widely used for data exchange between a server and a web application, as well as between different components of a system. In Python, working with JSON is straightforward, and the built-in json
module provides functions to encode and decode JSON data. In this article, we’ll explore how to create and build JSON objects in Python.
