Can you explain what is meant by a fully implemented dataclass in Python?

A fully implemented dataclass in Python is a class created using the @dataclass decorator from the dataclasses module, which automatically generates methods such as __init__, __repr__, __eq__, and others based on the declared fields of the class.

This allows for quick creation of data-holding classes without the need to write a lot of boilerplate code.

Example of a fully implemented dataclass:

from dataclasses import dataclass

@dataclass
class Point:
    x: float
    y: float

p1 = Point(1.0, 2.0)
p2 = Point(1.0, 2.0)

print(p1)        # Point(x=1.0, y=2.0)
print(p1 == p2)  # True

Here, @dataclass automatically created the constructor, comparison method, and convenient string representation of the object.
