I don't understand what "predicting which member of the object" means? Do you mean that in the array, you have classes that contain ndarrays as their attributes, and the classes have __cmp__ implemented? If not, can you tell why def xcmp(a, b): a_nd = isinstance(a, ndarray) b_nd = isinstance(b, ndarray) if a_nd and b_nd: pass # compare ndarrays in some way elif a_nd: return 1 # sort ndarrays first elif b_nd: return -1 # sort ndarrays first else: return cmp(a, b) # ordinary compare does not work?
