PYTHON 与C相互交互调用实例解析

  PYTHON 与C相互交互调用实例解析
 使用前工具：Vc++编译器Python 解释器如没有装VC，可以去微软网站下一个C++的编译器，地址如下：http://download.microsoft.com/download/3/9/b/39bac755-0a1e-4d0b-b72c-3a158b7444c4/VCToolkitSetup.exe 装完后，在环境变量中把PYTHON的INCLUDE和LIBS分别加入下面2个宏INCLUDELIB 1、C中调用PYTHON#include <Python.h> int main(int argc, char *argv[]) { Py_Initialize(); PyRun_SimpleString("from time import time,ctime/n" "print 'Today is',ctime(time())/n"); Py_Finalize(); return 0; } 直接用CL 文件名  编译就是 2、用C生成DLL,用PYTHON调用C代码：如FOO.C#include <Python.h>/* Define the method table. */static PyObject *foo_bar(PyObject *self, PyObject *args);static PyMethodDef FooMethods[] = {{"bar",  foo_bar, METH_VARARGS},{NULL, NULL}};/* Here's the initialization function.  We don't need to do anythingfor our own needs, but Python needs that method table. */void initfoo(){(void) Py_InitModule("foo", FooMethods);}/* Finally, let's do something ... involved ... as an example function. */static PyObject *foo_bar(PyObject *self, PyObject *args){char *string;int   len;if (!PyArg_ParseTuple(args, "s", &string))return NULL;len = strlen(string);return Py_BuildValue("i", len);}C定义文件：foo.defEXPORTSinitfoo编译生成foo.dllCl -c foo.c;link foo.obj /dll /def:foo.def /OUT:foo.dll 在PYTHON中调用：Import fooDir(foo)…即可以看到结果：>>> import foo>>> dir(foo)['__doc__', '__file__', '__name__', 'bar']>>> ^Z   (注：文章然简单，但很适合初学者，还请笑纳 ：） )
