Subtle error in `getattr_hook` example in the Descriptor Guide

Documentation

The example below, from the Descriptor Guide, does not seem to reflect the behaviour of the actual implementation.

https://github.com/python/cpython/blob/ced2691de4c9500ac9a5ccded00741a5fc2d9d2c/Doc/howto/descriptor.rst?plain=1#L733-L740

Unless I'm mistaken, line 736 return obj.__getattribute__(name) should actually read return type(obj).__getattribute__(obj, name).

It's easy to miss when thinking of class instances, but the issue becomes more evident when the example is applied to an attribute lookup on a class object instead. The example would call the __getattribute__ method of the class itself, while the actual implementation calls __getattribute__ on the metaclass (not to mention that in this case the call in the example would fail, due to a missing argument, as it is calling a plain function, rather than a bound method).

Ouvrez Doc/howto/descriptor.rst autour des lignes 733-740 et comparez l’exemple de getattr_hook avec le comportement de l’implémentation décrit dans l’issue, en particulier pour la recherche d’attributs des objets de classe. Si l’écart est confirmé, mettez à jour l’expression de retour documentée et vérifiez que le guide correspond à l’implémentation.
