Pending removal in Python 3.16 ¶

• The import system:

  • 设置 __loader__ on a module while failing to set __spec__.loader is deprecated. In Python 3.16, __loader__ will cease to be set or taken into consideration by the import system or the standard library.

• array :

  • The 'u' format code ( wchar_t ) has been deprecated in documentation since Python 3.3 and at runtime since Python 3.13. Use the 'w' format code ( Py_UCS4 ) for Unicode characters instead.

• asyncio :

  • asyncio.iscoroutinefunction() is deprecated and will be removed in Python 3.16, use inspect.iscoroutinefunction() instead. (Contributed by Jiahao Li and Kumar Aditya in gh-122875 )。

• builtins :

  • Bitwise inversion on boolean types, ~True or ~False has been deprecated since Python 3.12, as it produces surprising and unintuitive results ( -2 and -1 ). Use not x instead for the logical negation of a Boolean. In the rare case that you need the bitwise inversion of the underlying integer, convert to int explicitly ( ~int(x) ).

• shutil :

  • The ExecError exception has been deprecated since Python 3.14. It has not been used by any function in shutil since Python 3.4, and is now an alias of RuntimeError .

• symtable :

  • The Class.get_methods method has been deprecated since Python 3.14.

• sys :

  • The _enablelegacywindowsfsencoding() function has been deprecated since Python 3.13. Use the PYTHONLEGACYWINDOWSFSENCODING environment variable instead.

• tarfile :

  • The undocumented and unused TarFile.tarfile attribute has been deprecated since Python 3.13.
