"The sole value of the type ``NoneType``. ``None`` is frequently used to "

msgstr ""

"``NoneType`` 类型的唯一值。 ``None`` 经常用于表示缺少值，当因为默认参数未传递给函数时。 给 ``None`` "

"Special value which should be returned by the binary special methods (e.g. "

":meth:`__eq__`, :meth:`__lt__`, :meth:`__add__`, :meth:`__rsub__`, etc.) to "

"indicate that the operation is not implemented with respect to the other "

"type; may be returned by the in-place binary special methods (e.g. "

msgstr ""

"双目运算特殊方法（如 :meth:`__eq__`, :meth:`__lt__`, :meth:`__add__`, :meth:`__rsub__`"

" 等）应返回的特殊值，用于表示运算没有针对其他类型的实现；也可由原地双目运算特殊方法（如 :meth:`__imul__`, "

":meth:`__iand__` 等）出于同样的目的而返回。 它不应被作为布尔值来解读。"

"When a binary (or in-place) method returns ``NotImplemented`` the "

"interpreter will try the reflected operation on the other type (or some "

"other fallback, depending on the operator). If all attempts return "

"``NotImplemented``, the interpreter will raise an appropriate exception. "

"Incorrectly returning ``NotImplemented`` will result in a misleading error "

"message or the ``NotImplemented`` value being returned to Python code."

msgstr ""

"当二进制（或就地）方法返回 ``NotImplemented`` 时，解释器将尝试对另一种类型（或其他一些回滚操作，取决于运算符）的反射操作。 "

"如果所有尝试都返回 ``NotImplemented`` ，则解释器将引发适当的异常。 错误返回的 ``NotImplemented`` "

"将导致误导性错误消息或返回到Python代码中的 ``NotImplemented`` 值。"

"``NotImplementedError`` 和 ``NotImplemented`` 不可互换，即使它们有相似的名称和用途。 "

"有关何时使用它的详细信息，请参阅 :exc:`NotImplementedError`。"

"Evaluating ``NotImplemented`` in a boolean context is deprecated. While it "

"The same as the ellipsis literal \"``...``\". Special value used mostly in "

msgstr ""

":mod:`site` 模块（在启动期间自动导入，除非给出 :option:`-S` 命令行选项）将几个常量添加到内置命名空间。 它们对交互式解释器 "
