From: moerchendiser2k3 on 16 Mar 2010 07:52 Hi, i have a serious problem and I am looking for a solution. I pass an instance of a class from a file to PyObject_Call. When something fails, I get a full traceback. If it succeeds, I get the return value. Is it possible to get information from which line/file the return value of PyObject_Call is? Thanks!! moerchendiser2k3

Could you explain what you want to do with this information and in what cases you need it? Do you want to extract the information programmatically at runtime? Stefan |
