How to implement JSON serialization and deserialization?

JSON serialization and deserialization can be achieved through relevant libraries or tools provided by programming languages. Taking Python as an example, we will explain how to implement JSON serialization and deserialization.

JSON Serialization:
The json library in Python allows for the serialization of Python objects into a JSON string. This can be achieved using the json.dumps() function for JSON serialization.

import json

data = {'name': 'John', 'age': 30, 'city': 'New York'}
json_str = json.dumps(data)
print(json_str)

The output is as follows:

{"name": "John", "age": 30, "city": "New York"}

Deserializing JSON:
The json library in Python also offers a method to deserialize a JSON string into a Python object. This can be achieved using the json.loads() function for deserializing JSON.

import json

json_str = '{"name": "John", "age": 30, "city": "New York"}'
data = json.loads(json_str)
print(data)

Output result:

{'name': 'John', 'age': 30, 'city': 'New York'}

The examples above demonstrate how to perform JSON serialization and deserialization using Python’s json library. In fact, most programming languages provide similar JSON serialization and deserialization functions, so you just need to refer to the specific language’s documentation or library to use them.
