Python Metaclasses By: Rajesh P.S.Python is an object-oriented language that simplifies working with classes. A class in Python defines specific behaviors for its instances, which are objects in Python. These class instances are created using the class as a blueprint. Similarly, a metaclass in...

Everything is an object in Python, including classes. Hence, if classes are an object, they must be created by another class also called as Metaclass. So, a metaclass is just another class that creates class objects. Usually,typeis the built-in metaclass Python uses for every class. But w...
In Python, objects are instances of classes. A class is a blueprint or template that defines a set of attributes (variables) and methods (functions) common to all objects of that class. Data and behavior are encapsulated in objects, which represent real-world entities or abstract concepts. He...
Dataclasses are a way to make friendly classes in Python while avoiding common boilerplate code.How do dataclasses work?This is a dataclass:from dataclasses import dataclass @dataclass class Point: x: float y: float That x: float and y: float syntax is called type hinting or type ...
But classes are more than that in Python. Classes are objects too. Yes, objects. As soon as you use the keywordclass, Python executes it and creates an OBJECT. The instruction >>> class ObjectCreator(object): ... pass ... creates in memory an object with the name "ObjectCreator". ...
Metaclasses are a advanced concept in Python and are not often used in everyday programming. They are used to modify the behavior of a class, as well as the behavior of objects created from that class. Here is an example of how you might use a metaclass to create a class: class MyMet...

In Python classes, instance variables are variables that are unique to each instance (object) of the class. They are defined within the class and used to store data specific to individual objects. It is possible for objects of the same class to have their own independent data through instance...
