# Pending removal in Python 3.15

- The import system:

  - Setting `__cached__` on a module while failing to set `__spec__.cached` is deprecated. In Python 3.15, `__cached__` will cease to be set or take into consideration by the import system or standard library. (gh-97879)

  - Setting `__package__` on a module while failing to set `__spec__.parent` is deprecated. In Python 3.15, `__package__` will cease to be set or take into consideration by the import system or standard library. (gh-97879)

- `ctypes`:

  - La función indocumentada `ctypes.SetPointerType()` ha quedado obsoleta desde Python 3.13.

- `http.server`:

  - The obsolete and rarely used `CGIHTTPRequestHandler` has been deprecated since Python 3.13. No direct replacement exists. Anything is better than CGI to interface a web server with a request handler.

  - El indicador `--cgi` a la interfaz de línea de comandos python -m http.server ha quedado obsoleto desde Python 3.13.

- `importlib`:

  - `load_module()` method: use `exec_module()` instead.

- `pathlib`:

  - `.PurePath.is_reserved()` has been deprecated since Python 3.13. Use `os.path.isreserved()` to detect reserved paths on Windows.

- `platform`:

  - `platform.java_ver()` has been deprecated since Python 3.13. This function is only useful for Jython support, has a confusing API, and is largely untested.

- `sysconfig`:

  - The check_home argument of `sysconfig.is_python_build()` has been deprecated since Python 3.12.

- `threading`:

  - `RLock()` will take no arguments in Python 3.15. Passing any arguments has been deprecated since Python 3.14, as the Python version does not permit any arguments, but the C version allows any number of positional or keyword arguments, ignoring every argument.

- `types`:

  - `types.CodeType`: Accessing `codeobject.co_lnotab` was deprecated in PEP 626 since 3.10 and was planned to be removed in 3.12, but it only got a proper `DeprecationWarning` in 3.12. May be removed in 3.15. (Contributed by Nikita Sobolev in gh-101866.)

- `typing`:

  - The undocumented keyword argument syntax for creating `NamedTuple` classes (for example, `Point = NamedTuple("Point", x=int, y=int)`) has been deprecated since Python 3.13. Use the class-based syntax or the functional syntax instead.

  - When using the functional syntax of `TypedDict`s, failing to pass a value to the fields parameter (`TD = TypedDict("TD")`) or passing `None` (`TD = TypedDict("TD", None)`) has been deprecated since Python 3.13. Use `class TD(TypedDict): pass` or `TD = TypedDict("TD", {})` to create a TypedDict with zero field.

  - The `typing.no_type_check_decorator()` decorator function has been deprecated since Python 3.13. After eight years in the `typing` module, it has yet to be supported by any major type checker.

- `sre_compile`, `sre_constants` and `sre_parse` modules.

- `wave`:

  - The `getmark()`, `setmark()` and `getmarkers()` methods of the `Wave_read` and `Wave_write` classes have been deprecated since Python 3.13.

- `zipimport`:

  - `zipimport.zipimporter.load_module()` has been deprecated since Python 3.10. Use `exec_module()` instead. (gh-125746.)
