# Pending removal in Python 3.15

- La función `PyImport_ImportModuleNoBlock()`: use `PyImport_ImportModule()` en su lugar.

- `PyWeakref_GetObject()` and `PyWeakref_GET_OBJECT()`: Use `PyWeakref_GetRef()` instead. The pythoncapi-compat project can be used to get `PyWeakref_GetRef()` on Python 3.12 and older.

- El tipo `Py_UNICODE` y macro `Py_UNICODE_WIDE`: use `wchar_t` en su lugar.

- `PyUnicode_AsDecodedObject()`: Use `PyCodec_Decode()` instead.

- `PyUnicode_AsDecodedUnicode()`: Use `PyCodec_Decode()` instead; Note that some codecs (for example, «base64») may return a type other than `str`, such as `bytes`.

- `PyUnicode_AsEncodedObject()`: Use `PyCodec_Encode()` instead.

- `PyUnicode_AsEncodedUnicode()`: Use `PyCodec_Encode()` instead; Note that some codecs (for example, «base64») may return a type other than `bytes`, such as `str`.

- Python initialization functions, deprecated in Python 3.13:

  - `Py_GetPath()`: Use `PyConfig_Get("module_search_paths")` (`sys.path`) instead.

  - `Py_GetPrefix()`: Use `PyConfig_Get("base_prefix")` (`sys.base_prefix`) instead. Use `PyConfig_Get("prefix")` (`sys.prefix`) if virtual environments need to be handled.

  - `Py_GetExecPrefix()`: Use `PyConfig_Get("base_exec_prefix")` (`sys.base_exec_prefix`) instead. Use `PyConfig_Get("exec_prefix")` (`sys.exec_prefix`) if virtual environments need to be handled.

  - `Py_GetProgramFullPath()`: Use `PyConfig_Get("executable")` (`sys.executable`) instead.

  - `Py_GetProgramName()`: Use `PyConfig_Get("executable")` (`sys.executable`) instead.

  - `Py_GetPythonHome()`: Use `PyConfig_Get("home")` or the `PYTHONHOME` environment variable instead.

  The pythoncapi-compat project can be used to get `PyConfig_Get()` on Python 3.13 and older.

- Functions to configure Python’s initialization, deprecated in Python 3.11:

  - `PySys_SetArgvEx()`: Set `PyConfig.argv` instead.

  - `PySys_SetArgv()`: Set `PyConfig.argv` instead.

  - `Py_SetProgramName()`: Set `PyConfig.program_name` instead.

  - `Py_SetPythonHome()`: Set `PyConfig.home` instead.

  - `PySys_ResetWarnOptions()`: Borre `sys.warnoptions` y `warnings.filters` en su lugar.

  The `Py_InitializeFromConfig()` API should be used with `PyConfig` instead.

- Global configuration variables:

  - `Py_DebugFlag`: Use `PyConfig.parser_debug` or `PyConfig_Get("parser_debug")` instead.

  - `Py_VerboseFlag`: Use `PyConfig.verbose` or `PyConfig_Get("verbose")` instead.

  - `Py_QuietFlag`: Use `PyConfig.quiet` or `PyConfig_Get("quiet")` instead.

  - `Py_InteractiveFlag`: Use `PyConfig.interactive` or `PyConfig_Get("interactive")` instead.

  - `Py_InspectFlag`: Use `PyConfig.inspect` or `PyConfig_Get("inspect")` instead.

  - `Py_OptimizeFlag`: Use `PyConfig.optimization_level` or `PyConfig_Get("optimization_level")` instead.

  - `Py_NoSiteFlag`: Use `PyConfig.site_import` or `PyConfig_Get("site_import")` instead.

  - `Py_BytesWarningFlag`: Use `PyConfig.bytes_warning` or `PyConfig_Get("bytes_warning")` instead.

  - `Py_FrozenFlag`: Use `PyConfig.pathconfig_warnings` or `PyConfig_Get("pathconfig_warnings")` instead.

  - `Py_IgnoreEnvironmentFlag`: Use `PyConfig.use_environment` or `PyConfig_Get("use_environment")` instead.

  - `Py_DontWriteBytecodeFlag`: Use `PyConfig.write_bytecode` or `PyConfig_Get("write_bytecode")` instead.

  - `Py_NoUserSiteDirectory`: Use `PyConfig.user_site_directory` or `PyConfig_Get("user_site_directory")` instead.

  - `Py_UnbufferedStdioFlag`: Use `PyConfig.buffered_stdio` or `PyConfig_Get("buffered_stdio")` instead.

  - `Py_HashRandomizationFlag`: Use `PyConfig.use_hash_seed` and `PyConfig.hash_seed` or `PyConfig_Get("hash_seed")` instead.

  - `Py_IsolatedFlag`: Use `PyConfig.isolated` or `PyConfig_Get("isolated")` instead.

  - `Py_LegacyWindowsFSEncodingFlag`: Use `PyPreConfig.legacy_windows_fs_encoding` or `PyConfig_Get("legacy_windows_fs_encoding")` instead.

  - `Py_LegacyWindowsStdioFlag`: Use `PyConfig.legacy_windows_stdio` or `PyConfig_Get("legacy_windows_stdio")` instead.

  - `Py_FileSystemDefaultEncoding`, `Py_HasFileSystemDefaultEncoding`: Use `PyConfig.filesystem_encoding` or `PyConfig_Get("filesystem_encoding")` instead.

  - `Py_FileSystemDefaultEncodeErrors`: Use `PyConfig.filesystem_errors` or `PyConfig_Get("filesystem_errors")` instead.

  - `Py_UTF8Mode`: Use `PyPreConfig.utf8_mode` or `PyConfig_Get("utf8_mode")` instead. (see `Py_PreInitialize()`)

  The `Py_InitializeFromConfig()` API should be used with `PyConfig` to set these options. Or `PyConfig_Get()` can be used to get these options at runtime.
