Using these variables as "another mechanism for changing face
appearance" never really worked, since mode authors were free to use the
face instead of the variable (i.e. quoting the symbol). This means that
when users customized the variables, it would change its appearance only
in some cases, which is a rather surprising interface.
Indeed, it turns out that some modes have not always been consistent,
and mixed using the variable and the face, increasing the confusion even
further. Thus, the only thing users could rely on to always work was to
leave the variables at their default value, and to customize the face.
We now recommend customizing the face, and are obsoleting these
variables. This will lead to some minor code-churn, but it is believed
that it will be ultimately worth it. To fix existing Lisp code, you
should typically only need to quote the symbol, as this commit shows.
It might be the case that we will have to keep the obsolete variables,
that have been with us since Emacs 19, around for a longer time-period
than normal, to allow package authors to adapt.

declare now-unused variable.
Now that 'treesit-font-lock-level' can be a number or a list, it
should be handled using 'treesit--compute-font-lock-level'.
* lisp/progmodes/python.el (python--treesit-fontify-string):
Apply 'treesit--compute-font-lock-level' to
'treesit-font-lock-level'.
* lisp/progmodes/python.el (python--font-lock-f-strings): Bind
'parse-sexp-ignore-comments' to nil so that we can look for
closing braces even if a hash is used in the format specifier.
* test/lisp/progmodes/python-tests.el
(python-font-lock-f-string-1): New test. (Bug#74738)
* lisp/progmodes/python.el (python--auto-mode-alist-regexp): Don't use
rx in autoloaded variable, since it breaks bootstrap when copied to
ldefs-boot.el.
* lisp/ldefs-boot.el: Update.
* lisp/progmodes/python.el (python-font-lock-keywords-level-2)
(python--treesit-special-attributes): Update special attributes,
making it current for Python 3.13.
* lisp/progmodes/python.el: Define 'subword-mode' before its use
in 'python-mode-map' so invoking menu-bar-open in a python-mode
buffer does not cause a void-variable error when subword-mode is
not loaded, menu-bar-mode is disabled and debug-on-error is enabled.
It's okay to use defvar-keymap here since the 'compat' package backports
it for all versions of Emacs that we support (24.4 or later).
* lisp/progmodes/python.el (python-mode-map): Prefer defvar-keymap.
(python-menu): Move to toplevel.
SCons is a build system whose associated files are Python scripts.
Ref: https://www.scons.org/doc/0.96/HTML/scons-user/x325.html
* lisp/progmodes/python.el (python--auto-mode-alist-regexp):
Use 'python-mode' for SCons build files.
* lisp/progmodes/python.el: Remove out-of-date documentation about
automatic indentation; 'electric-indent-mode' is enabled by default in
Emacs 24.4 or later, so this is no longer an issue.
Prefer whatever version of Python that "python" might point to; use
"python3" if it doesn't exist. On recent versions of typical GNU/Linux
distributions, "python" either does not exist or it points to Python 3.
In (presumed rare) cases where "python" points to Python 2 instead,
users are now expected to manually customize these variables if they
want to use Python 3.
* lisp/progmodes/python.el (python-interpreter)
(python-shell-interpreter): Prefer "python" to "python3".

(python-font-lock-keywords-maximum-decoration)
(python--treesit-exceptions): Add all built-in exceptions in Python 3.13
as keywords. Missing from the list was "BaseExceptionGroup",
"EncodingWarning", "ModuleNotFoundError", and "PythonFinalizationError".
