The array of pointers alone would be roughly 4GB on a 32-bit build, so there's no way that'll ever fit... on a 64-bit build, that'll take up 8GBish for the list, plus probably 24 bytes minimum per integer, so even if there's absolutely no heap overhead, you're still looking at 32GB to store that list. Yeeeouch. I think we can drop the "slightly" from your description! For comparison, a 64-bit Python 3 says: >>> sys.getsizeof(range(0, 1000000000000000, 999937)) 48 Thanks, much nicer. ChrisA
