":pep:`492` introduced support for native coroutines and ``async`` / "

"implementation is that it was not possible to use ``await`` and ``yield`` in "

"`~object.__set_name__` method. Whenever a new class is defined, the new "

"method will be called on all descriptors included in the definition, "

"providing them with a reference to the class being defined and the name "

"given to the descriptor within the class namespace. In other words, "

"instances of descriptors can now know the attribute name of the descriptor "

"in the owner class::"

msgstr ""

msgid ":ref:`Feature documentation <descriptors>`"

msgstr ""

msgid "PEP 519: Adding a file system path protocol"

msgstr ""

msgid ""

"File system paths have historically been represented as :class:`str` or :"

"class:`bytes` objects. This has led to people who write code which operate "

"on file system paths to assume that such objects are only one of those two "

"types (an :class:`int` representing a file descriptor does not count as that "

"is not a file path). Unfortunately that assumption prevents alternative "

"object representations of file system paths like :mod:`pathlib` from working "

"with pre-existing code, including Python's standard library."

msgstr ""

msgid ""

"To fix this situation, a new interface represented by :class:`os.PathLike` "

"has been defined. By implementing the :meth:`~os.PathLike.__fspath__` "

"method, an object signals that it represents a path. An object can then "

"provide a low-level representation of a file system path as a :class:`str` "

"or :class:`bytes` object. This means an object is considered :term:`path-"

"like <path-like object>` if it implements :class:`os.PathLike` or is a :"

"class:`str` or :class:`bytes` object which represents a file system path. "

"Code can use :func:`os.fspath`, :func:`os.fsdecode`, or :func:`os.fsencode` "

"to explicitly get a :class:`str` and/or :class:`bytes` representation of a "

"path-like object."

msgstr ""

msgid ""

"The built-in :func:`open` function has been updated to accept :class:`os."

"PathLike` objects, as have all relevant functions in the :mod:`os` and :mod:"

"`os.path` modules, and most other functions and classes in the standard "

"library. The :class:`os.DirEntry` class and relevant classes in :mod:"

"`pathlib` have also been updated to implement :class:`os.PathLike`."

msgstr ""

msgid ""

"The hope is that updating the fundamental functions for operating on file "

"system paths will lead to third-party code to implicitly support all :term:"

"`path-like objects <path-like object>` without any code changes, or at least "

"very minimal ones (e.g. calling :func:`os.fspath` at the beginning of code "

"before operating on a path-like object)."

msgstr ""

msgid ""

"In most world locations, there have been and will be times when local clocks "

"are moved back. In those times, intervals are introduced in which local "

"clocks show the same time twice in the same day. In these situations, the "

"information displayed on a local clock (or stored in a Python datetime "

msgstr ""

msgid ""

"Representing filesystem paths is best performed with str (Unicode) rather "

"than bytes. However, there are some situations where using bytes is "

"sufficient and correct."

msgstr ""

msgid ""

"Prior to Python 3.6, data loss could result when using bytes paths on "

"Windows. With this change, using bytes to represent paths is now supported "

"on Windows, provided those bytes are encoded with the encoding returned by :"

"func:`sys.getfilesystemencoding()`, which now defaults to ``'utf-8'``."

msgstr ""

"While Python provides extensive support to customize how code executes, one "

"The :func:`~asyncio.ensure_future` function and all functions that use it, "

"such as :meth:`loop.run_until_complete() <asyncio.loop.run_until_complete>`, "

"now accept all kinds of :term:`awaitable objects <awaitable>`. (Contributed "
