Question

哪位高手知道这个python的返回值在C++中怎么获取

Answer 1

　写一个cpp文件， 比如叫 abc.cpp //abc.cpp #include "Python.h" PyObject* _user_add( PyObject *self, PyObject *args ) { int xx; int yy; int zz; if (!PyArg_ParseTuple(args, "i|i", &xx,&yy)) return NULL; zz = xx+yy; return Py_BuildValue("i", zz); } static PyMethodDef User_Methods[] = { {"add", _user_add, METH_VARARGS, "add two numbers."}, {NULL, NULL, 0, NULL} /* Sentinel */ }; PyMODINIT_FUNC inituser(void) { (void) Py_InitModule("user", User_Methods); } 然后写一个setup.py # setup.py import distutils from distutils.core import setup, Extension module_user = Extension("user", sources = ["abc.cpp"]) setup(name = "My User Extension", version = "1.0", ext_modules = [module_user]) 然后编译安装这个c++扩展 python setup.py install 应该就可以用了 >>> import user >>> user.add(8,9) 试试看噢。
