Some other points... If you care about efficiency and want to use json, don't use the one that comes packaged with the standard library. There are lots of third-party json packages (ujson is the one we use) which are significantly faster. Not sure if that's true of the newest python releases, but it was certainly true in 2.6. The advantage of pickle over json is that pickle can serialize many types of objects that json can't. The other side of the coin is that pickle is python-specific, so if you think you'll ever need to read your data from other languages, pickle is right out. -- http://mail.python.org/mailman/listinfo/python-list
