"The deallocation function can cause arbitrary Python code to be invoked "
"(e.g. when a class instance with a :meth:`__del__` method is deallocated). "
"While exceptions in such code are not propagated, the executed code has free"
" access to all Python global variables. This means that any object that is "
"reachable from a global variable should be in a consistent state before "
":c:func:`Py_DECREF` is invoked. For example, code to delete an object from "
"a list should copy a reference to the deleted object in a temporary "
"variable, update the list data structure, and then call :c:func:`Py_DECREF` "
"for the temporary variable."
msgstr ""
"释放函数可导致任意 Python 代码被发起调用（例如当一个带有 :meth:`__del__` 方法的类实例被释放时就是如此）。 "
"虽然此类代码中的异常不会被传播，但被执行的代码能够自由访问所有 Python 全局变量。 这意味着任何可通过全局变量获取的对象在 "
":c:func:`Py_DECREF` 被发起调用之前都应当处于完好状态。 "
"例如，从一个列表中删除对象的代码应当将被删除对象的引用拷贝到一个临时变量中，更新列表数据结构，然后再为临时变量调用 "
":c:func:`Py_DECREF`。"

"The warning for :c:func:`Py_DECREF` does not apply with respect to the "
