出学python,问个导出的小问题

[星羽]

cpp的代码

#include "windows.h"
#include "stdio.h"
#include "python.h"

class test

public :
    test()
        : levl(0)

    }

    void setLevel(int _levl)
    {
        levl = _levl;

    {
        return levl;
    }

    static void _pyInit(test* self, PyObject* args)
    {
        (*self->name) = 0;
        self->levl = 0;
    }

    static void _pyDest(test* self)
    {
        Py_TYPE(self)->tp_free((PyObject*)self);
    }

    static PyObject* _py_setName(test* self, PyObject* args)
    {
        Py_INCREF(Py_None);

        const char* name = 0;

        if (PyArg_ParseTuple(args, "s", &name))  
        {
            strncpy(self->name, name, sizeof(self->name));
        }
        
        return Py_None;
    }
    
public :
    PyObject_HEAD
    char name[128];
    int  levl;
};

static PyMethodDef _py_test_method[] =

    { "setName", (PyCFunction)test::_py_setName, METH_VARARGS, "get name" },
    { NULL, NULL, NULL, NULL }

static PyTypeObject _py_test_class =

    PyModuleDef_HEAD_INIT,  
    "test_module",             
    "test_module",

int main()
{
    Py_Initialize();

    if (!Py_IsInitialized())
        return 1;

    PyObject* module = 0;  
    _py_test_class.tp_new = PyType_GenericNew;       

    if (PyType_Ready(&_py_test_class) < 0)  
        return 1;  

    module = PyModule_Create(&_py_test_module);         
    
    if (!module)  
        return 1;  

    Py_INCREF(&_py_test_module);  

    PyModule_AddObject(module, "test", (PyObject*)&_py_test_class); 
    PyRun_SimpleString("exec(open('py.py').read())");

    Py_Finalize();

    return 0;
}

py.py 的代码

import test_module

print(dir())

执行 PyRun_SimpleString("exec(open('py.py').read())");的时候报错了
:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "<string>", line 7, in <module>
ImportError: No module named test_module

找不到模块 - -b

[星羽]

python的版本是3.2.2

[星羽]

自己搞定了 - -b

顺便问一下,如果把一个对象做为参数传给python的函数去处理?

[CCDDR]

python只能处理python对象，
如果是从C++传进去的对象，那么这个对象是要定义成PYTHON对象的，比如
PyObject* m_pPythonObject;
m_pPythonObject就可以当成参数传给python去处理

[iambic]

http://docs.python.org/extending/embedding.html
可以用PyObject_CallObject调用函数。

[wangjiepro]

使用boost.python库可以方便地导入导出
