Why, exactly? By zipping the state, you make it utterly opaque. It'll require some sort of tool to tease it apart before you can read anything. Much more useful would be to have some sort of textual delimiter, followed by the content - then when you come to read it, all you need is a text viewer. Disk space is not expensive. Even if you manage to cut your file by a factor of four (75% compression, which is entirely possible if your content is plain text, but far from guaranteed), that's maybe three years of Moore's Law at most. You can get 3-4 terabytes of storage for roughly $100-$200, depending on exactly where you buy it, which dollar you're using, etc. How long will your program have to run to generate that much data? If you can't do that in, say, two years, don't bother compressing. ChrisA -- https://mail.python.org/mailman/listinfo/python-list
