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>. |
