Why do you want holes? Is the issue that you're storing sparse data and don't want to waste memory on unused keys? If so, a dictionary should do you fine. Do you need to be able to read the values back out in a specific order? You can still do that with a dictionary if you're willing to re-sort the keys; that's O(n log n) on the number of keys, but if n is small, it doesn't matter. -- https://mail.python.org/mailman/listinfo/python-list
