What is the difference between a dataclass and a regular class in Python?

A dataclass in Python is a decorator that automatically generates special methods like init() and repr() for classes, making it easier to create classes that are primarily used to store data. In contrast, a regular class requires you to define these methods manually.

Can you give me an example of a dataclass?

Sure! Here's a simple example:

from dataclasses import dataclass

@dataclass
class Person:
    name: str
    age: int

This creates a Person class with name and age attributes, and automatically generates the init and repr methods.

What are the advantages of using dataclasses?

Dataclasses reduce boilerplate code, improve readability, and provide built-in methods for comparison and representation, making them ideal for data storage.

Are there any limitations to using dataclasses?

Yes, dataclasses are best suited for simple data structures. They may not be ideal for complex classes that require extensive custom behavior or inheritance.
