函数对象
有一些特定于 Python 函数的函数。
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.

PyObject PyFunction_GetCode
(PyObject **op)
Return value: Borrowed reference.
返回与函数对象 op 关联的代码对象。
PyObject PyFunction_GetGlobals
(PyObject **op)
Return value: Borrowed reference.
返回与函数对象op相关联的全局字典。
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
。
PyObject PyFunction_GetAnnotations
(PyObject **op)
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.
失败时引发 SystemError 异常并返回 -1
。
