New submission from Kevin Shweh <kevin.sh...@gmail.com>: The data model docs for __new__ say "If __new__() is invoked during object construction and it returns an instance or subclass of cls, then the new instance’s __init__() method will be invoked..."
"instance or subclass of cls" is incorrect - if for some reason __new__ returns a subclass of cls, __init__ will not be invoked, unless the subclass also happens to be an instance of cls (which can happen with metaclasses). This should probably say something like "instance of cls (including subclass instances)", or "instance of cls or of a subclass of cls", or just "instance of cls". ---------- assignee: docs@python components: Documentation messages: 401065 nosy: Kevin Shweh, docs@python priority: normal severity: normal status: open title: Error in __new__ docs versions: Python 3.10, Python 3.11, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue45104> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
