v3 = Vector3D(10, -7, 3)

print('Before: ', v3)

data = v3.serialize()

print('Serialized:', data)

print('After: ', deserialize(data))

>>>

Before: Vector3D(10, -7, 3)

Serialized: {"class": "Vector3D", "args": [10, -7, 3]}

After: Vector3D(10, -7, 3)

Using metaclasses for class registration ensures that you’ll never miss a class as long as the inheritance tree is right. This works well for serialization, as I’ve shown, and also applies to database object-relationship mappings (ORMs), plug-in systems, and system hooks.
