函式(Function)物件¶
這有一些少數Python函數的於具體說明。
-
PyFunctionObject
¶ 用于函数的 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)¶ Return true if o is a function object (has type
PyFunction_Type
). The parameter must not be 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。
The function’s docstring and name are retrieved from the code object. __module__ is retrieved from globals. The argument defaults, annotations and closure are set to NULL. __qualname__ is set to the same value as the function’s name.
-
PyObject*
PyFunction_NewWithQualName
(PyObject *code, PyObject *globals, PyObject *qualname)¶ - Return value: New reference.
As
PyFunction_New()
, but also allows setting the function object’s__qualname__
attribute. qualname should be a unicode object or NULL; if NULL, the__qualname__
attribute is set to the same value as its__name__
attribute.3.3 版新加入.
-
PyObject*
PyFunction_GetGlobals
(PyObject *op)¶ - Return value: Borrowed reference.
回傳與全域函數字典相關的函數物件 op。
-
PyObject*
PyFunction_GetModule
(PyObject *op)¶ - Return value: Borrowed reference.
返回函数对象 op 的 __module__ 属性,通常为一个包含了模块名称的字符串,但可以通过 Python 代码设为返回其他任意对象。
-
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.
失败时引发
SystemError
异常并返回-1
。
-
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.
失败时引发
SystemError
异常并返回-1
。
-
int
PyFunction_SetAnnotations
(PyObject *op, PyObject *annotations)¶ 設定函數物件 op 的標註。annotations 必須是一個字典或 Py_None。
失败时引发
SystemError
异常并返回-1
。
