What are the key features of data classes in Python?

Data classes in Python provide a decorator to automatically generate special methods like init(), repr(), and eq(). They simplify class creation.

Can you explain how to create a data class?

Sure! You can create a data class by using the @dataclass decorator from the dataclasses module. For example:

from dataclasses import dataclass

@dataclass
class Point:
    x: int
    y: int

What advantages do data classes offer over regular classes?

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

Are there any limitations to using data classes?

Yes, data classes are mutable by default, which may not be suitable for all use cases. Also, they don't support inheritance as flexibly as regular classes.
