我想这个可以参考boost.python或者SWIG的源码吧，这个需要你对Python的对象模型非常了解才能了然于胸 ：）

也许我该马上看看boost，希望不会太难！

我重新描述下我的问题：
既然python与c++要交互，必然存在一个共享对象，c++中和python脚本共同操作的！
如果使用面向过程的方式而不用对象的话，不是很难，我想我应该能够搞定了！

如果要共享对象的话，我有个不是很优雅的解决方案
宿主提供过程化的函数接口 ---------->
脚本根据宿主提供的函数写一个基类包装宿主提供的函数接口---------->
宿主程序包装基类的函数。
--------------------因为python对象在c语言中都是PyObject（没错吧）
//===========================================================
以上描述指针对我所遇到的问题

不知道大家有没有什么方式能够直接在宿主中提供对象借口给python
我昨天尝试了一下，显示错误信息是不能从__thiscall  转换，强制转换应该不行吧？没试过！

好吧，简化一下问题
怎么把一个宿主语言中的对象共享给python脚本？

我建议你还是用正统的Python的C扩展方式，用一个C的dll包装你的C++的class，呵呵，这个不会耽误你太多时间 ：）

从网上看到的一个例子（有C代码和PYTHON代码），应该可以解决你的问题。

谢谢，不过光有这些还不够。
我想能不能直接传个对象的引用给c程序呢？
经过测试似乎不行：

#include "python.h"
#include 
#include 

extern "C" __declspec (dllexport) PyObject * tankforward(PyObject
*self,PyObject * args)
{
 return Py_BuildValue("i",PyInstance_Check(args));
}

static PyMethodDef tankmethod[]=
{
 {"forward",tankforward,METH_VARARGS,NULL},
 {NULL,NULL}
};

int main(int argc,char ** argv)
{
 Py_Initialize();
 Py_InitModule("tank",tankmethod);
 PyRun_SimpleString("import tank\n"
      "class myTank:\n"
      "\t\"this is my tank\"\n"
      "\tdef test(self):\n"
      "\t\tprint 'its a test'\n"
      "c=myTank()\n"
         "print tank.forward(c)"
       );
 Py_Finalize();
 return 0;
}
//-------------------------------------------------------------------------------------------------------------------------

tank.forward(c)是传了含有一个myTank对象的tuple给c函数，

而c函数PyObject * tankforward(PyObject *self,PyObject * args)
我查了下资料，需要一个tuple参数

 return Py_BuildValue("i",PyInstance_Check(args));

可是为什么返回的是0呢？或者说我传过来的不是PyInstance?

args不是一个tuple吗？你用PyInstance_Check检查自然应该是False吧

可以试试
PyObject *instance = NULL;
PyArg_Parse(args, "(O)", &instance;);
然后用PyObject_CallMethod调用instance

没有试过，可能语法有些什么错误，比如说&instance;应该是instance等等...
你调试一下吧 ：）
