Edit Question
Title
Body
I've always set up metaclasses something like this: class SomeMetaClass(type): def __new__(cls, name, bases, dict): #do stuff here But I just came across a metaclass that was defined like this: class SomeMetaClass(type): def __init__(self, name, bases, dict): #do stuff here Is there any reason to prefer one over the other? Update : Bear in mind that I'm asking about using __new__ and __init__ in a metaclass. I already understand the difference between them in another class. But in a metaclass, I can't use __new__ to implement caching because __new__ is only called upon class creation in a metaclass.
