Python Tip.

The @dataclass decorator automatically generates standard methods like init, repr, and eq based on the class attributes.

Example 👇

# with dataclass
from dataclasses import dataclass

@dataclass
class Point:
    x: int
    y: int

Here's how it would look without @dataclass:

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):
        return (self.x, self.y) == (other.x, other.y)

dataclass saves time and eliminates boilerplate code when a class simply stores data.
