3- Immutability: Another key difference between normal classes and data classes is immutability. By default, data classes are immutable, meaning that their attributes cannot be modified after they are created. In contrast, normal classes are mutable by default, meaning that their attributes can be modified at any time.Dataclasses are python classes, but are suited for storing data objects.As discussed above, dataclasses are specifically used for the representation of data and its storage. Therefore the two most popular use cases of dataclasses are for printing a class and for equality checks.
What is the difference between object and Dataclass in Python : Objects do not provide default values for attributes. Named tuples do not provide default values for attributes, but the field names and values can be specified using keyword arguments. Data classes provide default values for attributes, which can be useful for handling missing or optional data.

As compared to regular python class, python data class enforces type annotations for data fields. On top of it, Pydantic offers additional features like raising errors for type violation and data validation.
What is a dataclass : A data class is a class typically containing mainly data, although there aren't really any restrictions. It is created using the new @dataclass decorator, as follows: Python. from dataclasses import dataclass @dataclass class DataClassCard: rank: str suit: str.
A data class is a class that only contains state and does not perform any operation. The advantage of using data classes instead of regular classes is that Kotlin gives us an immense amount of self-generated code.
One of the key benefits of data classes is the automatic generation of commonly used methods. By simply using the @dataclass decorator, Python generates methods like __init__ , __repr__ , __eq__ , and __hash__ for you.

6. Conclusion. In this article, we describe the types and classes in programming. Types (or data types) ensure data integrity and provide compile-time checking, while classes facilitate code organization, code reuse, and modularization through object-oriented principles.A class is a code template for creating objects. Objects have member variables and have behaviour associated with them. In python a class is created by the keyword class . An object is created using the constructor of the class. This object will then be called the instance of the class.A normal class can be defined with or without a parameter in its constructor. Data classes have default implementations for the following methods using only properties that were declared in the primary constructor; toString(), hashCode(), copy(), componentN(), equals().

What is a class in data : A data class is a list of data set allocation attributes and their values. You cannot assign a data class to an object; however, data class may be used for allocation of a scratch tape to be used to write objects.
What is a class in programming : In object-oriented programming, a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods). The user-defined objects are created using the class keyword.
What is class vs def in Python
class is used to define a class (a template from which you can instantiate objects). def is used to define a function or a method. A method is like a function that belongs to a class.
The Application class in Android is the base class within an Android app that contains all other components such as activities and services. The Application class, or any subclass of the Application class, is instantiated before any other class when the process for your application/package is created.Classes provide a means of bundling data and functionality together. Creating a new class creates a new type of object, allowing new instances of that type to be made. Each class instance can have attributes attached to it for maintaining its state.
What is class in Python with example : In Python, a class is a user-defined data type that contains both the data itself and the methods that may be used to manipulate it. In a sense, classes serve as a template to create objects. They provide the characteristics and operations that the objects will employ. Suppose a class is a prototype of a building.
