(original) (raw)

An alternative I am fond of is to to avoid introducing a new type, and simply initialize a PyObject \* and register its address. �For example:

�PyObject \*tmp;
�static PyObject \*s\_update; � �// pick a naming convention

�PY\_IDENTIFIER\_INIT(update);
�tmp = PyObject\_CallMethodObj(result, s\_update, "O", other);

�(but also PyObject\_GetAttr(o, s\_update), etc.)

PY\_IDENTIFIER\_INIT(update) might expand to something like:

�if (!s\_update) {
� �s\_update = PyUnicode\_InternFromString("update");
� �\_Py\_IdentifierAdd(&s\_update);
�}
