The docs already have that:

   PyObject* PyList_GetItem (PyObject *list, int index)

   Return value: Borrowed reference.

          Returns the object at position pos in the list pointed to by p.
          If pos is out of bounds, returns NULL and sets an IndexError
          exception.

   PyObject* PyList_New (int len)

   Return value: New reference.

          Returns a new list of length len on success, or NULL on
          failure.

   PyObject* PyList_GetSlice (PyObject *list, int low, int high)

   Return value: New reference.

          Returns a list of the objects in list containing the objects
          between low and high. Returns NULL and sets an exception if
          unsuccessful. Analogous to list[low:high].

And:

   int PyList_SetItem (PyObject *list, int index, PyObject *item)
          Sets the item at index index in list to item. Note: This
          function `steals'' a reference to item.
