Create an empty list (PyList_New(0)) and then append  (PyList_Append)
items (PyFloat_FromDouble) as you loop over this array variable. I'm
considering for some reason you don't know the size of this variable,
so it has a sentinel in the end, but if it is not the case you can
create a list with its final size and then use PyList_SetItem.
