builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.
* Add API to allow extensions to set callback function on creation and destruction of PyCodeObject

These slots are marked "should be treated as read-only" in the
table at the start of the document. That doesn't say anything about
setting them in the static struct.
`tp_bases` docs did say that it should be ``NULL`` (TIL!). If you
ignore that, seemingly nothing bad happens. However, some slots
may not be inherited, depending on which sub-slot structs are present.
(FWIW, NumPy sets tp_bases and is affected by the quirk -- though to
be fair, its DUAL_INHERIT code probably predates tp_bases docs, and
also the result happens to be benign.)
This patch makes things explicit.
It also makes the summary table legend easier to scan.

* Change documentation for sys.float_info.rounds
Change the documentation for sys.float_info.rounds to remove
references to C99 section 5.2.4.2.2 and instead place the
available values inline.
* Correction to previous documentation change
Newlines were not preserved in generated HTML on previous
commit. I have changes the list to a comma-separated list
of values and their meanings.
* Clarify source for value of FLT_ROUNDS
Clarify the source of the FLT_ROUNDS value and
change 'floating-point addition' to 'floating-point
arithmetic' to indicate that the rounding mode
applies to all arithmetic operations.
The docs stated that PyImport_ImportFrozenModuleObject() returns a
new reference, but it actually returns an int.

A opy of #98549, whose author (@icecream17) uses a school computer that blocks the CLA site. I did not mention this in commit comment above so CLA bot does not pick up the name and request the CLA again.
* nail down a couple examples to have more predictable output
* update a number of things, but this is really just a stash...
* added an applications section to describe typical uses for native and machine-independent formats
* make sure all format strings use a format prefix character
* responding to comments from @gpshead. Not likely finished yet.
* This got more involved than I expected...
* respond to several PR comments
* a lot of wordsmithing
* try and be more consistent in use of ``x`` vs ``'x'``
* expand examples a bit
* update the "see also" to be more up-to-date
* original examples relied on import * so present all examples as if
* reformat based on @gpshead comment (missed before)
* responding to comments
* missed this
* one more suggested edit
* wordsmithing
Fix potential race condition in code patterns:
* Replace "Py_DECREF(var); var = new;" with "Py_SETREF(var, new);"
* Replace "Py_XDECREF(var); var = new;" with "Py_XSETREF(var, new);"
* Replace "Py_CLEAR(var); var = new;" with "Py_XSETREF(var, new);"
Other changes:
* Replace "old = var; var = new; Py_DECREF(var)"
with "Py_SETREF(var, new);"
* Replace "old = var; var = new; Py_XDECREF(var)"
with "Py_XSETREF(var, new);"
* And remove the "old" variable.
On some platforms, and in particular macOS/arm64, the calling
convention for variadic arguments is different from the regular
calling convention. Add a section to the documentation to document
this.
The ``structmember.h`` header is deprecated, though it continues to be available
and there are no plans to remove it. There are no deprecation warnings. Old code
can stay unchanged (unless the extra include and non-namespaced macros bother
you greatly). Specifically, no uses in CPython are updated -- that would just be
unnecessary churn.
The ``structmember.h`` header is deprecated, though it continues to be
available and there are no plans to remove it.
Its contents are now available just by including ``Python.h``,
with a ``Py`` prefix added if it was missing:
- `PyMemberDef`, `PyMember_GetOne` and`PyMember_SetOne`
- Type macros like `Py_T_INT`, `Py_T_DOUBLE`, etc.
(previously ``T_INT``, ``T_DOUBLE``, etc.)
- The flags `Py_READONLY` (previously ``READONLY``) and
`Py_AUDIT_READ` (previously all uppercase)
Several items are not exposed from ``Python.h``:
- `T_OBJECT` (use `Py_T_OBJECT_EX`)
- `T_NONE` (previously undocumented, and pretty quirky)
- The macro ``WRITE_RESTRICTED`` which does nothing.
- The macros ``RESTRICTED`` and ``READ_RESTRICTED``, equivalents of
`Py_AUDIT_READ`.
- In some configurations, ``<stddef.h>`` is not included from ``Python.h``.
It should be included manually when using ``offsetof()``.
The deprecated header continues to provide its original
contents under the original names.
Your old code can stay unchanged, unless the extra include and non-namespaced
macros bother you greatly.
There is discussion on the issue to rename `T_PYSSIZET` to `PY_T_SSIZE` or
similar. I chose not to do that -- users will probably copy/paste that with any
spelling, and not renaming it makes migration docs simpler.

os.remove can raise PermissionError instead of IsADirectoryError,
when the object to be removed is a directory (in particular on
macOS).
This reverts a change done in #14262.
# DOC: Improvements in library/stdtypes
This PR does the following:
1. Replaces :meth: by :func: around repr function
2. Adds links to Unicode Standard site
3. Makes explicit "when" you can call the `iskeyword` function. The previous text could cause confusion to readers, especially those with English as a second language. The reader could understand that the `isidentifier` method calls the `iskeyword` function. Now, it is explicit that the dev can do it.
4. Replaces a URL with an inline link.
