Using dataclasses

If you want to define a class to store information without additional methods, you can use dataclass. In a few lines, you can define it.

from dataclasses import dataclass

@dataclass
class Point:
    x: int
    y: int

And you can use it to create an object. As you can see, it also allows you to print the point with its attributes.

p = Point(10, 20)
print(p)
# Point(x=10, y=20)

They do not really add anything new. You can write code with the same behavior as shown. But it contains a lot of boilerplate code.

class Point:
    def __init__(self, x: int, y: int):
        self.x = x
        self.y = y

    def __repr__(self):
        return f"Point(x={self.x}, y={self.y})"

    def __eq__(self, other):
        if isinstance(other, Point):
            return self.x == other.x and self.y == other.y
        return False

In short, dataclass allows you to define a simple class while saving code.
