you're not providing enough arguments; "iii" means three pointers, not
one.  try:

    PyArg_Parse(return, "(iii)", array, array+1, array+2)

instead.  or, if you prefer maximum clarity:

    PyArg_Parse(return, "(iii)", &array[0], &array[1], &array[2])

(I assume you left out the error handling code; ignoring the return value
from PyArg_Parse is not a good idea)
