函数对象¶
有一些特定于 Python 函数的函数。
-
PyFunctionObject
¶ 用于功能的 C 结构体。
-
PyTypeObject
PyFunction_Type
¶ 这是一个
PyTypeObject
实例并表示 Python 函数类型。 它作为types.FunctionType
向 Python 程序员公开。
-
int
PyFunction_Check
(PyObject *o)¶ 如果 o 是函数对象(具有类型
PyFunction_Type
),则返回 true 。 参数不能为 NULL 。
-
PyObject*
PyFunction_New
(PyObject *code, PyObject *globals)¶ - Return value: New reference.
返回与代码对象 code 关联的新函数对象。 globals 必须是一个字典,该函数可以访问全局变量。
从代码对象中检索函数的 docstring 和 name 。 __module__ 从 globals 中检索。 参数 defaults 、 annotations 和 closure 设置为*NULL* 。 __qualname__ 设置为与函数名称相同的值。
-
PyObject*
PyFunction_NewWithQualName
(PyObject *code, PyObject *globals, PyObject *qualname)¶ - Return value: New reference.
如
PyFunction_New()
,但也允许设置函数对象的__qualname__
属性。 qualname 应该是 unicode 对象或 NULL ;如果为 NULL ,则__qualname__
属性设置为与__name__
属性相同的值。3.3 新版功能.
-
PyObject*
PyFunction_GetGlobals
(PyObject *op)¶ - Return value: Borrowed reference.
Return the globals dictionary associated with the function object op.
-
PyObject*
PyFunction_GetModule
(PyObject *op)¶ - Return value: Borrowed reference.
Return the __module__ attribute of the function object op. This is normally a string containing the module name, but can be set to any other object by Python code.
-
PyObject*
PyFunction_GetDefaults
(PyObject *op)¶ - Return value: Borrowed reference.
Return the argument default values of the function object op. This can be a tuple of arguments or NULL.
-
int
PyFunction_SetDefaults
(PyObject *op, PyObject *defaults)¶ Set the argument default values for the function object op. defaults must be Py_None or a tuple.
Raises
SystemError
and returns-1
on failure.
-
PyObject*
PyFunction_GetClosure
(PyObject *op)¶ - Return value: Borrowed reference.
Return the closure associated with the function object op. This can be NULL or a tuple of cell objects.
-
int
PyFunction_SetClosure
(PyObject *op, PyObject *closure)¶ Set the closure associated with the function object op. closure must be Py_None or a tuple of cell objects.
Raises
SystemError
and returns-1
on failure.
-
PyObject *
PyFunction_GetAnnotations
(PyObject *op)¶ - Return value: Borrowed reference.
Return the annotations of the function object op. This can be a mutable dictionary or NULL.
-
int
PyFunction_SetAnnotations
(PyObject *op, PyObject *annotations)¶ Set the annotations for the function object op. annotations must be a dictionary or Py_None.
Raises
SystemError
and returns-1
on failure.
