When I read <Descriptor HowTo Guide> (python 3.6.1 version), I found there is a concept of 'unbound method' in some places. However, when I referred to <What’s New In Python 3.0>, it said the concept of “unbound methods” has been removed from the language.
So I wondered if there should be a change in <Descriptor HowTo Guide> python3 version?
For instance, in this code example of the guide:
When I tested myself, the result of statement "D.f" should be <function> not <unbound method>.
