Have you used the dataclass decorator in your projects?

Yes, the @dataclass decorator in Python is used to automatically add standard methods to a class, such as __init__, __repr__, __eq__, and others, which significantly reduces boilerplate code.

Example of usage:

from dataclasses import dataclass

@dataclass
class Point:
    x: int
    y: int

p = Point(1, 2)
print(p)  # Point(x=1, y=2)

This is convenient for classes that mainly store data, such as DTOs, configurations, or computation results.
