New submission from Michael Lee: For some reason, the section of the typing docs about Optional stated that Optional[T] was equivalent to Union[T, type(None)]. While this is true, it's somewhat inconsistent and potentially confusing since everywhere else in the docs, we just use None.
This patch modifies that line to use Union[T, type(None)] instead, and moves the line explaining that None is special-cased to mean type(None) to the first usage of None as a type within the docs. ---------- assignee: docs@python components: Documentation files: update-none-vs-type-none.patch keywords: patch messages: 275718 nosy: docs@python, gvanrossum, michael0x2a priority: normal severity: normal status: open title: Update documentation about None vs type(None) in typing versions: Python 3.5, Python 3.6, Python 3.7 Added file: http://bugs.python.org/file44542/update-none-vs-type-none.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue28073> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
