Python JSON

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

Example:

Python3

import json

# JSON string
employee = '{"id":"09", "name": "Nitin", "department":"Finance"}'

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

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

Output:

 {'id': '09', 'name': 'Nitin', 'department': 'Finance'}
<class 'dict'>


{
    "id": "09",
    "name": "Nitin",
    "department": "Finance"
}
<class 'str'>
