Pending Removal in Python 3.16

  • :mod:`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)).
  • :mod:`array`:
    • The 'u' format code (:c:type:`wchar_t`) has been deprecated in documentation since Python 3.3 and at runtime since Python 3.13. Use the 'w' format code (:c:type:`Py_UCS4`) for Unicode characters instead.
  • :mod:`shutil`:
    • The :class:`!ExecError` exception has been deprecated since Python 3.14. It has not been used by any function in :mod:`!shutil` since Python 3.4, and is now an alias of :exc:`RuntimeError`.
  • :mod:`symtable`:
    • The :meth:`Class.get_methods <symtable.Class.get_methods>` method has been deprecated since Python 3.14.
  • :mod:`sys`:
    • The :func:`~sys._enablelegacywindowsfsencoding` function has been deprecated since Python 3.13. Use the :envvar:`PYTHONLEGACYWINDOWSFSENCODING` environment variable instead.
  • :mod:`tarfile`:
    • The undocumented and unused :attr:`!TarFile.tarfile` attribute has been deprecated since Python 3.13.
