No, OrderedDict works fine. Just in answer to your question about why this particular feature isn't there: 1) The slicing thing is conceptually not that well defined. To me it was obvious what you meant but I suspect that many people would find it confusing or unexpected. (see e.g. the initial responses from Steve and Ben in this thread) 2) The OrderedDict isn't really that deeply thought out beyond "I want a dict that has a consistent iteration order". -- Oscar _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
