What are metaclasses

Metaclasses are a powerful feature in Python that allow you to define the behavior and properties of classes themselves, rather than their instances. In simpler terms, a metaclass is a class of a class that defines how a class behaves. A metaclass is typically used to create APIs, enforce coding standards, or apply design patterns at the class level.

By default, all classes in Python are instances of the type metaclass (`type`), but you can create your own metaclasses by defining a class that inherits from `type`.

Example of Metaclass in Python:

class Meta(type): def __new__(cls, name, bases, attrs): # Custom behavior during class creation return super(Meta, cls).__new__(cls, name, bases, attrs) class MyClass(metaclass=Meta): pass print(type(MyClass)) # Output:

metaclasses python class behavior type custom classes programming
