Hello, first of all, I am a programming newbie, especially in python...
Onwards to the problem, I have been having difficulty embedding a python module into my C/C++ program. (just a test program before moving on into the real thing). I have been making test runs using the codes from http://docs.python.org/ext/pure-embedding.html as a basic, but modifiying it now as a function inside my C/C++ code. Problem started when I started passing an array as an argument. The module also need an array as an argument, but somehow I can't make them to go pass the "input-error checking" of the module. The code for argument building and calling are as follows: void CallSnake(char ModName[], char FuncName[], double result[]) { ... /*Some operations to import modname, and preping FuncName, all is ok*/ ... /*Processing the result array and calling the function, problem time*/ pArgs = PyTuple_New(MAX_ELEMENT); pArg = PyList_New(1); for (i = 0; i < MAX_ELEMENT; ++i) { pValue = Py_BuildValue("d", result[i]); PyTuple_SetItem(pArgs, i, pValue); if (!(*pArgs).ob_refcnt) { Py_DECREF(pArgs); Py_DECREF(pModule); fprintf(stderr, "Cannot convert argument\n"); return; } } PyList_SetItem(pArg, 0, pArgs); pValue = PyObject_CallFunctionObjArgs(pFunc,pArg,NULL); /*Some more checking and DECREFing occurs here*/ } Error I have been getting is: Traceback if x.ndim != 1; /*x is the input array, checking if it's a 1D*/ AttributeError: 'list' object has no attribute 'ndim' I have been trying many call variations, but alas, I think the problem lies in the list building process. I have no problems calling a non- arrayed (albeit,still single) argument. Thanks in advance... -- http://mail.python.org/mailman/listinfo/python-list
