This document is for an old version of Python that is no longer supported. You should install the python3 and python3-doc packages and read the Python documentation for the Python3 version packaged in this release.

# Function Objects

There are a few functions specific to Python functions.

type 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 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, name and __module__ are retrieved from the code object, the argument defaults and closure are set to NULL.

PyObject *PyFunction_GetCode(PyObject *op)

  Return the code object associated with the function object op.

PyObject *PyFunction_GetGlobals(PyObject *op)

  Return the globals dictionary associated with the function object op.

PyObject *PyFunction_GetModule(PyObject *op)

  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 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 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.
