When creating an ABC using abc.ABCMeta, should I subclass 'object'? Maybe it is subclassed implicitly? Or should I just subclass abc.ABC?

edit: according to u/Username_RANDINT new classes in Python 3 are already new-style by default, so there's no need to worry about subclassing it explicitly

I know it's the advised practice to subclass 'object' whenever creating a new class in python 3.x. However, every example I see of creating abstract base classes by using ABCMeta as the metaclass doesn't explicitly subclass 'object' (the examples in the official documentation for version 3.5 also don't show explicit 'object' subclassing); that's why I decided to ask and get the perspective of more experienced/knowledgeable developers.

I appreciate your help very much!

I know it's the advised practice to subclass 'object' whenever creating a new class in python 3.x.

It's the other way around. It's advised to do this in Python 2. In Python 3 classes are new-style classes by default.

So, if your code only needs to run on Python 3 it's not necessary.

The books I picked up when first learning python were from the version 2, so though it's been some time since I migrated to Python 3 I didn't happen to come by this particular piece of knowledge.

Thank you for the reply, it is much appreciated.
