Apr 23, 2021 · dataclass module is introduced in Python 3.7 as a utility tool to make structured classes specially for storing data. These classes hold certain properties and functions to deal specifically with the data and its representation. Although the module was introduced in Python3.7, one can also use it in Python3.6 by installing dataclasses library.

Data classes, a feature introduced in Python 3.7, are a type of class mainly used for storing data. They come with basic functionality already implemented, such as instance initialization, printing, and comparison. For simple data structures, you have probably already used a tuple or a dict.

Data classes are just regular classes that are geared towards storing state, rather than containing a lot of logic. Every time you create a class that mostly consists of attributes, you make a data class. What the dataclasses module does is to make it easier to create data classes. It takes care of a lot of boilerplate for you.

Aug 6, 2021 · DataClasses has been added in a recent addition in python 3.7 as a utility tool for storing data. DataClasses provides a decorator and functions for automatically adding generated special methods such as __init__ () , __repr__ () and __eq__ () to user-defined classes.

Nov 1, 2022 · The dataclasses module, a feature introduced in Python 3.7, provides a way to create data classes in a simpler manner without the need to write methods.

Mar 15, 2024 · Let’s cover some of the fundamental concepts of Python data classes that make the so useful. Despite all their features, data classes are regular classes that take much less code to implement the same functionality. Here is the Exercise class again: @dataclass class Exercise: . name: str . reps: int . sets: int . weight: float . 'Bench press'

Oct 27, 2024 · Python DataClasses make creating simple classes (commonly used to store data) much easier by including many boilerplate methods. These classes were introduced in Python 3.7 (back in 2018!) and can be accessed using the standard Python library. In this tutorial, you’ll learn how to: Let’s dive in! What are Python’s Data Classes?

Mar 20, 2025 · In this article, will walk you through what Python Data Classes are, how to use them, and why they’re useful. Read Also: Object Oriented Programming in Python. What Are Data Classes? Data Classes are a type of class specifically designed for storing data and it is introduced in Python 3.7.

Python dataclasses were introduced in Python 3.7. They provide a powerful way to create classes focused on storing data. This guide will explore how dataclasses reduce boilerplate code, enhance readability, and offer powerful features for modern Python development.
