I assume you don't include the memory required by the function itself. Integers take 20 bytes, but rounded to the nearest multiple of 8 bytes, so 24 bytes. However, we can assume that the 0 int is cached, so we only need 24 bytes for all n of them. Lists have a fixed overhead of 28 bytes, plus 4*n for the items, again rounded to the nearest multiple of 8 bytes. Add them together, and you have the memory usage of the list returned. -- Steven -- http://mail.python.org/mailman/listinfo/python-list
