Pending Removal in Python 3.15 ¶

• The import system:

  • 设置 __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 )

  • 设置 __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 :

  • The undocumented ctypes.SetPointerType() function has been deprecated since 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.

  • The --cgi flag to the python -m http.server command-line interface has been deprecated since Python 3.13.

• locale :

  • The getdefaultlocale() function has been deprecated since Python 3.11. Its removal was originally planned for Python 3.13 ( gh-90817 ), but has been postponed to Python 3.15. Use getlocale() , setlocale() ，和 getencoding() instead. (Contributed by Hugo van Kemenade in gh-111187 )。

• pathlib :

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

• 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.

• 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 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 (e.g. Point = NamedTuple("Point", x=int, y=int) ) has been deprecated since Python 3.13. Use the class-based syntax or the functional syntax instead.

  • 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.

• wave :

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