New submission from Géry <gery.o...@gmail.com>: The [language documentation](https://docs.python.org/3/reference/datamodel.html#invoking-descriptors) states:
> Data descriptors with __set__() and __get__() defined always override a > redefinition in an instance dictionary. In contrast, non-data descriptors can > be overridden by instances. This override is not limited to data descriptors defining `__set__()` (and `__get__()`). It is also true for data descriptors defining `__delete__()` (and `__get__()`) and data descriptors defining both `__set__()` and `__delete__()` (and `__get__()`). In other words, _any_ data descriptors (objects defining either `__set__()` or `__delete__()` or both) defining `__get__()` override an attribute redefinition in an instance dictionary. ---------- assignee: docs@python components: Documentation messages: 353685 nosy: docs@python, maggyero priority: normal severity: normal status: open title: Remove the __set__ method restriction on data descriptors for attribute lookup precedence type: enhancement versions: Python 3.7 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38336> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
