函式（Function）物件

這有一些少數Python函數的於具體說明。

PyFunctionObject

The C structure used for functions.

PyTypeObject PyFunction_Type

This is an instance of PyTypeObject and represents the Python function type. It is exposed to Python programmers as types.FunctionType.

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.

Return a new function object associated with the code object code. globals must be a dictionary with the global variables accessible to the function.

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.

回傳與程式碼物件相關的函數物件 op。

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.

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)

回傳函式物件 op 標註。此可以是一個可變動的字典或 NULL。

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。

Raises SystemError and returns -1 on failure.
