What is Python Class Metaclass?
A Python class metaclass is a class of a class that defines how a class behaves. In Python, everything is an object, including classes themselves. Metaclasses allow you to customize class creation by overriding methods like `__new__` and `__init__`. This enables developers to modify class attributes, enforce coding standards, or implement design patterns at the class level. By using metaclasses, you can create classes dynamically, add new methods, or alter existing ones, providing powerful tools for advanced programming techniques and frameworks. Essentially, metaclasses give you control over class instantiation and behavior in Python.
