New submission from debuggy: 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:

...

...

class D(object): ... def f(self, x): ... return x ... d = D() D.__dict__['f'] # Stored internally as a function <function f at 0x00C45070> D.f # Get from a class becomes an unbound method <unbound method D.f> d.f # Get from an instance becomes a bound method <bound method D.f of <__main__.D object at 0x00B18C90>>

When I tested myself, the result of statement "D.f" should be <function> not <unbound method>. ---------- assignee: docs@python components: Documentation messages: 293160 nosy: debuggy, docs@python priority: normal severity: normal status: open title: Why is there a concept "unbound method" in <Descriptor HowTo Guide> python3 version? type: enhancement versions: Python 3.6 _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue30292> _______________________________________
