What is dataclass serialization in Python?

Dataclass serialization refers to converting Python dataclass instances into a format that can be easily stored or transmitted, like JSON.

How do I serialize a dataclass to JSON?

You can use the json module along with asdict() from the dataclasses module to serialize a dataclass to JSON.

Can you show me an example?

Sure! Here's a simple example:

from dataclasses import dataclass, asdict
import json

@dataclass
class Person:
    name: str
    age: int

person = Person(name='Alice', age=30)
json_data = json.dumps(asdict(person))
print(json_data)

What about deserializing it back to a dataclass?

To deserialize, you can use json.loads() and then create a new instance of the dataclass with the loaded data.
