What is the difference between a class and a metaclass in Python?
Alex K

In Python, a class is a blueprint or template for creating objects, while a metaclass is a class that defines the behavior of other classes. The distinction lies in their roles and how they interact with objects and other classes. 1. Class: A class in Python is a user-defined type that encapsulates attributes (variables) and behaviors (methods) of objects. It defines the structure and behavior of objects that belong to it. When you create an instance (object) of a class, you are creating a specific instance that conforms to the attributes and behaviors defined in the class. Here's an example of a class in Python:

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

    def greet(self):
   print(f"Hello, my name is {self.name}.")

# Usage:
person = Person("Alice")
person.greet()  # Output: Hello, my name is Alice.

In the above code,Person is a class that represents a person. It has attributes (e.g.,name) and a behavior (e.g.,greet()) defined as methods. An instance of thePerson class,person, can be created with a specific name and can invoke thegreet() method. 2. Metaclass: A metaclass, sometimes referred to as a "class of classes," is a class that defines the behavior and structure of other classes. It allows you to customize the creation and behavior of classes. In Python, metaclasses are created by defining a class that subclasses thetype class. Here's an example of a metaclass in Python:

class SingletonMetaclass(type):
    _instances = {}

    def __call__(cls, *args, **kwargs):
   if cls not in cls._instances:
  cls._instances[cls] = super
