Python JSON

Python JSON JavaScript Object Notation is a format for structuring data. It is mainly used for storing and transferring data between the browser and the server. Python too supports JSON with a built-in package called JSON. This package provides all the necessary tools for working with JSON Objects including parsing, serializing, deserializing, and many more. 

JSON Example

Let’s see a simple example where we convert the JSON objects to Python objects and vice versa.

Convert from JSON to Python object

Let’s see a simple example where we convert the JSON objects to Python objects. Here, json.loads() method can be used to parse a valid JSON string and convert it into a Python Dictionary.

Python3

import json

# JSON string
employee = '{"id":"09", "name": "Nitin", "department":"Finance"}'
print("This is JSON", type(employee))

print("\nNow convert from JSON to Python")

# Convert string to Python dict
employee_dict = json.loads(employee)
print("Converted to Python", type(employee_dict))
print(employee_dict)

Output:

This is JSON <class 'str'>

Now convert from JSON to Python
Converted to Python <class 'dict'>
{'id': '09', 'name': 'Nitin', 'department': 'Finance'}

Convert from Python object to JSON

Let’s see a simple example where we convert Python objects to JSON objects. Here json.dumps() function will convert a subset of Python objects into a JSON string.

Python3

import json

# JSON string
employee_dict = {'id': '09', 'name': 'Nitin', 'department': 'Finance'}
print("This is Python", type(employee_dict))

print("\nNow Convert from Python to JSON")

# Convert Python dict to JSON
json_object = json.dumps(employee_dict, indent=4)
print("Converted to JSON", type(json_object))
print(json_object)

Output:

This is Python <class 'dict'>

Now Convert from Python to JSON
Converted to JSON <class 'str'>
{
    "id": "09",
    "name": "Nitin",
    "department": "Finance"
}
