From 50fe49c879af352914da3baa40c7fd1fb170028c Mon Sep 17 00:00:00 2001 From: Stephen Rosen Date: Tue, 2 Jun 2026 15:13:34 -0500 Subject: [PATCH] gh-150319: Replace all documentation which says "See PEP 585" (#150325) MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit * Replace all documentation which says "See PEP 585" The following classes in the stdlib get simple updates: - array.array - asyncio.Future - asyncio.Task - collections.defaultdict - collections.deque - contextvars.ContextVar - contextvars.Token - ctypes.Array - os.DirEntry - re.Match - re.Pattern - string.templatelib.Interpolation - string.templatelib.Template - types.MappingProxyType - queue.SimpleQueue - weakref.ref The following classes are documented publicly as functions, and are therefore updated internally (`__class_getitem__.__doc__`) but not in the public docs: - functools.partial - itertools.chain The following builtin types have updates to `__class_getitem__.__doc__` but not to any documentation pages: - BaseExceptionGroup - coroutines (from generators) - dict - enumerate - frozendict - frozenset - generators (and async generators) - list - memoryview - set - slice - tuple Special cases: - union objects are now documented as "supporting class-level []", rather than anything to do with generics. - Templates might be generic over a single type (union, in theory) or over a TypeVarTuple. As this is not currently fully settled, it is marked with a comment and a mild hint that it is a single type is used (namely, "type" is singular rather than "types", plural) * Apply suggestions from code review Co-authored-by: Jelle Zijlstra * Correct several class getitem docs And expand the text for tuples. Co-authored-by: Jelle Zijlstra <906600+JelleZijlstra@users.noreply.github.com> * Add notes on generic typing of builtins * Fix typo in tuple.__class_getitem__ docstring * Typo fix: malformed refs Fix `generic` links which weren't marked as `:ref:`. * Strike unnecessary docs on generic-ness Co-authored-by: Jelle Zijlstra <906600+JelleZijlstra@users.noreply.github.com> * Apply suggestions from code review These are applied at both the originally indicated locations and in the corresponding docstring definitions. Co-authored-by: Alex Waygood <66076021+AlexWaygood@users.noreply.github.com> * Update Doc/library/re.rst Co-authored-by: Alex Waygood * Update Objects/enumobject.c Co-authored-by: Alex Waygood * Remove tuple generic doc in 'stdtypes' page This is covered in more detail in the cross-linked typing documentation. The other copy of this documentation -- in the docstring for `tuple.__class_getitem__` -- is left in place. * Fix whitespace around new doc of generics Per review, do not introduce or remove whitespace such that section breaks are altered by the introduction of doc on various generic types. In most cases, this is a removal of an extra line. In one case (Arrays), it is the reintroduction of a line. Additionally, two other minor fixes are included: - incorrect indent on 'defaultdicts' - make `mappingproxy.__class_getitem__.__doc__` consistent with other mapping type generic docs Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com> * Move placement of memoryview generic note Previous placement was at the end of the main docstring, which is consistent with other types but places it after a section on various methods (which makes it read somewhat inconsistently). Moving it up helps resolve. Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com> * Ensure sphinxdoc does not start sentences lowercase Lowercase class names at the start of sentences are marked out with the `class` role. In the case of `deque`, documentation already refers to these as `Deques`, so this form is preferred. * Apply suggestions from code review Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com> * Fix line endings and wrap more tightly Line endings fixed by pre-commit ; also re-wrapped the MappingProxyType text which was too long. * Use 'ContextVars' style in sphinx doc --------- Co-authored-by: Jelle Zijlstra Co-authored-by: Jelle Zijlstra <906600+JelleZijlstra@users.noreply.github.com> Co-authored-by: Alex Waygood <66076021+AlexWaygood@users.noreply.github.com> Co-authored-by: Alex Waygood Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com> --- Doc/c-api/typehints.rst | 2 +- Doc/library/array.rst | 2 ++ Doc/library/asyncio-future.rst | 2 ++ Doc/library/asyncio-task.rst | 3 +++ Doc/library/collections.rst | 5 +++++ Doc/library/contextvars.rst | 6 ++++++ Doc/library/ctypes.rst | 2 ++ Doc/library/exceptions.rst | 3 +++ Doc/library/os.rst | 3 +++ Doc/library/queue.rst | 2 ++ Doc/library/re.rst | 6 ++++++ Doc/library/stdtypes.rst | 17 +++++++++++++++++ Doc/library/string.templatelib.rst | 2 ++ Doc/library/types.rst | 4 ++++ Doc/library/weakref.rst | 3 +++ Doc/reference/datamodel.rst | 3 +++ ...26-05-23-17-27-41.gh-issue-150319.ol9tWK.rst | 2 ++ Modules/_asynciomodule.c | 6 ++++-- Modules/_collectionsmodule.c | 10 ++++++++-- Modules/_ctypes/_ctypes.c | 2 +- Modules/_functoolsmodule.c | 3 ++- Modules/_queuemodule.c | 2 +- Modules/_sre/sre.c | 4 ++-- Modules/arraymodule.c | 3 ++- Modules/itertoolsmodule.c | 6 +++++- Modules/posixmodule.c | 2 +- Objects/descrobject.c | 2 +- Objects/dictobject.c | 6 ++++-- Objects/enumobject.c | 2 +- Objects/exceptions.c | 3 ++- Objects/genobject.c | 8 +++++--- Objects/interpolationobject.c | 2 +- Objects/listobject.c | 3 ++- Objects/memoryobject.c | 3 ++- Objects/setobject.c | 6 ++++-- Objects/sliceobject.c | 3 ++- Objects/templateobject.c | 6 +++++- Objects/tupleobject.c | 8 +++++++- Objects/unionobject.c | 3 ++- Objects/weakrefobject.c | 3 ++- Python/context.c | 6 ++++-- 41 files changed, 136 insertions(+), 33 deletions(-) create mode 100644 Misc/NEWS.d/next/Documentation/2026-05-23-17-27-41.gh-issue-150319.ol9tWK.rst diff --git a/Doc/c-api/typehints.rst b/Doc/c-api/typehints.rst index 98fe68737deb..ec2fba6da8b0 100644 --- a/Doc/c-api/typehints.rst +++ b/Doc/c-api/typehints.rst @@ -31,7 +31,7 @@ two types exist -- :ref:`GenericAlias ` and static PyMethodDef my_obj_methods[] = { // Other methods. ... - {"__class_getitem__", Py_GenericAlias, METH_O|METH_CLASS, "See PEP 585"} + {"__class_getitem__", Py_GenericAlias, METH_O|METH_CLASS, "my_obj is generic over its contained type"} ... } diff --git a/Doc/library/array.rst b/Doc/library/array.rst index ea5f23176da9..c688d54318e7 100644 --- a/Doc/library/array.rst +++ b/Doc/library/array.rst @@ -121,6 +121,8 @@ The module defines the following type: :exc:`TypeError` is raised.
