2-Minute Guide: dataclasses in Python

In Python, dataclasses provide a convenient way to create classes that mainly hold data. Let's compare a regular class with a @dataclass to see the benefits.

Regular Class

class Person:
    def __init__(self, name, age):
        self.name = name
        self.age = age

    def __repr__(self):
        return f"Person(name={self.name}, age={self.age})"

As you can see, we need to define __init__ and __repr__ methods manually.

@dataclass

python
from dataclasses import dataclass

@dataclass
