C API: PyXXX_SetItem

[Frank Sonnenburg]

Hi all,

am i right, that PyTuple_SetItem() and PyList_SetItem() only *transfer* 
references to objects, but don't increment reference counts?

And, in contrast, PyDict_SetItem() *does* increment the object reference 
count?


So,


        PyTuple_SetItem(tup,idx,PyInt_FromLong(123));

is perfect, but


        PyDict_SetItemString(dict,"key_name",PyInt_FromLong(123));

will lead to a memory leak. To avoid this:


        PyObject *py_int;
        py_int = PyInt_FromLong(123);
        PyDict_SetItemString(dict,"key_name",py_int);
        Py_DECREF(py_int);


I would appreciate any suggestions/corrections to this point. Thanks in 
advance
