Pending removal in Python 3.15
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
* The bundled copy of ``libmpdecimal``.
* The :c:func:`!PyImport_ImportModuleNoBlock`:
Use :c:func:`PyImport_ImportModule` instead.
* :c:func:`PyWeakref_GetObject` and :c:func:`PyWeakref_GET_OBJECT`:
Use :c:func:`PyWeakref_GetRef` instead. The `pythoncapi-compat project
<https://github.com/python/pythoncapi-compat/>`__ can be used to get
:c:func:`PyWeakref_GetRef` on Python 3.12 and older.
* :c:type:`Py_UNICODE` type and the :c:macro:`!Py_UNICODE_WIDE` macro:
Use :c:type:`wchar_t` instead.
* :c:func:`!PyUnicode_AsDecodedObject`:
Use :c:func:`PyCodec_Decode` instead.
* :c:func:`!PyUnicode_AsDecodedUnicode`:
Use :c:func:`PyCodec_Decode` instead; Note that some codecs (for example, "base64")
may return a type other than :class:`str`, such as :class:`bytes`.
* :c:func:`!PyUnicode_AsEncodedObject`:
Use :c:func:`PyCodec_Encode` instead.
* :c:func:`!PyUnicode_AsEncodedUnicode`:
Use :c:func:`PyCodec_Encode` instead; Note that some codecs (for example, "base64")
may return a type other than :class:`bytes`, such as :class:`str`.
* Python initialization functions, deprecated in Python 3.13:
* :c:func:`!Py_GetPath`:
Use :c:func:`PyConfig_Get("module_search_paths") <PyConfig_Get>`
(:data:`sys.path`) instead.
* :c:func:`!Py_GetPrefix`:
Use :c:func:`PyConfig_Get("base_prefix") <PyConfig_Get>`
(:data:`sys.base_prefix`) instead. Use :c:func:`PyConfig_Get("prefix")
<PyConfig_Get>` (:data:`sys.prefix`) if :ref:`virtual environments
<venv-def>` need to be handled.
* :c:func:`!Py_GetExecPrefix`:
Use :c:func:`PyConfig_Get("base_exec_prefix") <PyConfig_Get>`
(:data:`sys.base_exec_prefix`) instead. Use
:c:func:`PyConfig_Get("exec_prefix") <PyConfig_Get>`
(:data:`sys.exec_prefix`) if :ref:`virtual environments <venv-def>` need to
be handled.
* :c:func:`!Py_GetProgramFullPath`:
Use :c:func:`PyConfig_Get("executable") <PyConfig_Get>`
(:data:`sys.executable`) instead.
* :c:func:`!Py_GetProgramName`:
Use :c:func:`PyConfig_Get("executable") <PyConfig_Get>`
(:data:`sys.executable`) instead.
* :c:func:`!Py_GetPythonHome`:
Use :c:func:`PyConfig_Get("home") <PyConfig_Get>` or the
:envvar:`PYTHONHOME` environment variable instead.
The `pythoncapi-compat project
<https://github.com/python/pythoncapi-compat/>`__ can be used to get
:c:func:`PyConfig_Get` on Python 3.13 and older.
* Functions to configure Python's initialization, deprecated in Python 3.11:
* :c:func:`!PySys_SetArgvEx()`:
Set :c:member:`PyConfig.argv` instead.
* :c:func:`!PySys_SetArgv()`:
Set :c:member:`PyConfig.argv` instead.
* :c:func:`!Py_SetProgramName()`:
Set :c:member:`PyConfig.program_name` instead.
* :c:func:`!Py_SetPythonHome()`:
Set :c:member:`PyConfig.home` instead.
* :c:func:`PySys_ResetWarnOptions`:
Clear :data:`sys.warnoptions` and :data:`!warnings.filters` instead.
The :c:func:`Py_InitializeFromConfig` API should be used with
:c:type:`PyConfig` instead.
* Global configuration variables:
* :c:var:`Py_DebugFlag`:
Use :c:member:`PyConfig.parser_debug` or
:c:func:`PyConfig_Get("parser_debug") <PyConfig_Get>` instead.
* :c:var:`Py_VerboseFlag`:
Use :c:member:`PyConfig.verbose` or
:c:func:`PyConfig_Get("verbose") <PyConfig_Get>` instead.
* :c:var:`Py_QuietFlag`:
Use :c:member:`PyConfig.quiet` or
:c:func:`PyConfig_Get("quiet") <PyConfig_Get>` instead.
* :c:var:`Py_InteractiveFlag`:
Use :c:member:`PyConfig.interactive` or
:c:func:`PyConfig_Get("interactive") <PyConfig_Get>` instead.
* :c:var:`Py_InspectFlag`:
Use :c:member:`PyConfig.inspect` or
:c:func:`PyConfig_Get("inspect") <PyConfig_Get>` instead.
* :c:var:`Py_OptimizeFlag`:
Use :c:member:`PyConfig.optimization_level` or
:c:func:`PyConfig_Get("optimization_level") <PyConfig_Get>` instead.
* :c:var:`Py_NoSiteFlag`:
Use :c:member:`PyConfig.site_import` or
:c:func:`PyConfig_Get("site_import") <PyConfig_Get>` instead.
* :c:var:`Py_BytesWarningFlag`:
Use :c:member:`PyConfig.bytes_warning` or
:c:func:`PyConfig_Get("bytes_warning") <PyConfig_Get>` instead.
* :c:var:`Py_FrozenFlag`:
Use :c:member:`PyConfig.pathconfig_warnings` or
:c:func:`PyConfig_Get("pathconfig_warnings") <PyConfig_Get>` instead.
* :c:var:`Py_IgnoreEnvironmentFlag`:
Use :c:member:`PyConfig.use_environment` or
:c:func:`PyConfig_Get("use_environment") <PyConfig_Get>` instead.
* :c:var:`Py_DontWriteBytecodeFlag`:
Use :c:member:`PyConfig.write_bytecode` or
:c:func:`PyConfig_Get("write_bytecode") <PyConfig_Get>` instead.
* :c:var:`Py_NoUserSiteDirectory`:

Use :c:member:`PyConfig.buffered_stdio` or
:c:func:`PyConfig_Get("buffered_stdio") <PyConfig_Get>` instead.
* :c:var:`Py_HashRandomizationFlag`:
Use :c:member:`PyConfig.use_hash_seed`
and :c:member:`PyConfig.hash_seed` or
:c:func:`PyConfig_Get("hash_seed") <PyConfig_Get>` instead.

* :c:var:`!Py_FileSystemDefaultEncoding`, :c:var:`!Py_HasFileSystemDefaultEncoding`:
Use :c:member:`PyConfig.filesystem_encoding` or
:c:func:`PyConfig_Get("filesystem_encoding") <PyConfig_Get>` instead.
* :c:var:`!Py_FileSystemDefaultEncodeErrors`:
Use :c:member:`PyConfig.filesystem_errors` or
:c:func:`PyConfig_Get("filesystem_errors") <PyConfig_Get>` instead.

Use :c:member:`PyPreConfig.utf8_mode` or
:c:func:`PyConfig_Get("utf8_mode") <PyConfig_Get>` instead.
(see :c:func:`Py_PreInitialize`)
The :c:func:`Py_InitializeFromConfig` API should be used with
:c:type:`PyConfig` to set these options. Or :c:func:`PyConfig_Get` can be
used to get these options at runtime.
