Thank you, Good information, thank you. Was not aware of __set_name__.
IIRC that was one of the updates/improvements. Thanks to whomsoever...!
The:
instance.__dict__[self.name] = value
may require a bit of thought before it feels comfortable, but it is significantly easier to understand than what we had to do 'before'. I am using `setattr(instance, self.name, value)`. But I see that instance.__dict__ is more appropriate in this case.
Another surprise, and I've assumed you're asking in the context of [Custom] Descriptors, is in how many places/functions Python makes use of a descriptor/descriptor protocol. Yet few of us seem to make use of them in our application code... (YMMV!) I use them more and more.
However, I was more interested, why doesn't __set__ have an `owner` argument, while `__get__` does. I am aware that this is not an issue at all as one can simply do `inst.__class__`, but I am just curious about the reason for inconsistency. Although, answers that I got were very useful. DG
