@文心快码pyobject_callobject 返回null 文心快码 在Python的C API中,PyObject_CallObject 函数用于调用一个可调用对象(如函数、方法等)并传递参数。如果 PyObject_CallObject 返回NULL,这通常表示在调用过程中发生了错误。以下是一些可能的原因和相应的解决步骤: 确认PyObject_CallObject的使用环境和上下文: 确保你正在...
size(); ++i) { PyList_SetItem(p_rmax_zi, i, Py_BuildValue("d", rmax_zi[i])); } p_args = PyTuple_New(2); PyTuple_SetItem(p_args, 0, p_receive_depth); PyTuple_SetItem(p_args, 1, p_rmax_zi); PyObject* p_drmax = PyObject_CallObject(p_function, p_args); // 返回的...
PyObject_CallObject函数用于在Python中调用可调用对象。 它是Python C API里执行函数调用操作的关键函数。该函数定义在Python.h头文件中。PyObject_CallObject函数第一个参数为被调用的可调用对象。第二个参数是传递给被调用对象的参数元组。调用成功时返回函数调用的结果对象。若调用失败会返回NULL并设置异常信息。可调...
