可以用C写一个module，可提供给Python使用。
#include <Python.h>
#include <stdio.h>
void Print_PyObject(PyObject *obj)
{
Py_ssize_t size = 0;
PyObject *subObj = NULL;
PyObject *key = NULL;
Py_ssize_t pos = 0;
if (NULL == obj)
{
return;
}
if (Py_None == obj)
{
printf("obj is py_none");
}
else if(PyBool_Check(obj))
{
printf("obj is bool");
}
else if(PyInt_CheckExact(obj))
{
printf("obj is int : %ld\n", PyInt_AsLong(obj));
}
else if(PyFloat_CheckExact(obj))
{
printf("obj is Float: %f\n", PyFloat_AsDouble(obj));
}
else if(PyString_CheckExact(obj))
{
printf("obj is string:%s\n", PyString_AsString(obj));
}
else if(PyList_CheckExact(obj))
{
printf("obj is list\n");
size = PyList_Size(obj);
int idx = 0;
for (idx = 0; idx < size; idx++)
{
subObj = PyList_GetItem(obj, idx);
Print_PyObject(subObj);
}
}
else if(PyList_CheckExact(obj))
{
printf("obj is dict\n");
while (PyDict_Next(obj, &pos, &key, &subObj))
{
Print_PyObject(subObj);
}
}
}
static PyObject *PyExt_Set(PyObject *self, PyObject *args)
{
printf("PyExt_set!\n");
PyObject *newObject;
const char *uri;
if (!PyArg_ParseTuple(args, "sO!", &uri, &PyDict_Type, &newObject) &&
!PyArg_ParseTuple(args, "sO!", &uri, &PyList_Type, &newObject))
{
return Py_BuildValue("i", -1);
}
printf("uri:%s\n", uri);
return Py_BuildValue("i", 0);
}
static PyMethodDef PyExtMethods[] ={
{"Set", PyExt_Set, METH_VARARGS, "Perform Set Operation"},
{NULL, NULL, 0, NULL}
};
void initPyExt(void)
{
//PyImport_AddModule("PyExt");
Py_InitModule("PyExt", PyExtMethods);
}
在C module中会提供一个Set 方法。
然后编写setup.py
from distutils.core import setup, Extension
setup(name='PyExt', version='1.0', ext_modules=[Extension('PyExt', sources=['PyExt.c'])])
编译：python setup.py build
安装：python setup.py install
就可以在python中import PyExt了。
