Hi, I'm just wondering why <, <=, >=, and > are not supported by collections.OrderedDict:
>>> d1 = collections.OrderedDict((("a",1),("z",2),("k",3))) >>> d2 = d1.copy() >>> d2["z"] = 4 >>> d1 == d2 False >>> d1 < d2 Traceback (most recent call last): File "<pyshell#6>", line 1, in <module> d1 < d2 TypeError: unorderable types: OrderedDict() < OrderedDict() It just seems to me that since the items in ordered dictionaries are ordered, it would make sense to do an item by item comparison from first to last item in exactly the same way that Python compares lists or tuples? -- http://mail.python.org/mailman/listinfo/python-list
