Metaclasses in Python – The Power Behind Class Creation
In Python, everything is an object—including classes themselves! But who creates classes? The answer: Metaclasses. Metaclasses define how classes behave. They allow you to: ✅ Control class creation dynamically ✅ Modify class attributes and methods before instantiation ✅ Enforce coding standards or restrictions ✅ Prevent inheritance using metaclasses In this post, we’ll explore: ✔️ What metaclasses are ✔️ How Python classes are created ✔️ How to define custom metaclasses ✔️ Preventing inheritance using metaclasses ✔️ Real-world applications of metaclasses 1️⃣ Understanding Metaclasses: What Are They? In Python, a class is an instance of a metaclass. Just as objects are created from classes, classes themselves are created from metaclasses.
