How can I use dataclasses in my Python library?

You can use dataclasses to simplify the creation of classes that are primarily used to store data. They automatically generate special methods like init(), repr(), and eq().

Can you show me a simple example?

Sure! Here's a basic example:

from dataclasses import dataclass

@dataclass
class Book:
    title: str
    author: str
    year: int

my_book = Book(title='1984', author='George Orwell', year=1949)
print(my_book)

What are the benefits of using dataclasses?

Dataclasses reduce boilerplate code, improve readability, and provide built-in methods for comparison and representation.

Are there any limitations I should be aware of?

Yes, dataclasses are mutable by default, which can lead to unintended side effects. Also, they may not be suitable for all use cases, especially where immutability is required.
