I'm looking forward to an ordered dictionary in the standard library, especially for things like LRU caches. I was just reading the PEP, and caught this bit:
"Does OrderedDict.popitem() return a particular key/value pair? Yes. It pops-off the most recently inserted new key and its corresponding value." Okay, but I'd also like a convenient and fast way to find the oldest entry in an OrderedDict, which I think I'd need for an LRU cache. Skimming the current patch (od7.diff), I didn't notice one. Perhaps I simply missed something. Shouldn't popitem() allow the caller to choose which end from which to pop? _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
