 Dictionaries
 ============
 
-How can I get a dictionary to display its keys in a consistent order?
----------------------------------------------------------------------
-
-You can't.  Dictionaries store their keys in an unpredictable order, so the
-display order of a dictionary's elements will be similarly unpredictable.
-
-This can be frustrating if you want to save a printable version to a file, make
-some changes and then compare it with some other printed dictionary.  In this
-case, use the ``pprint`` module to pretty-print the dictionary; the items will
-be presented in order sorted by the key.
-
-A more complicated solution is to subclass ``dict`` to create a
-``SortedDict`` class that prints itself in a predictable order.  Here's one
-simpleminded implementation of such a class::
-
-   class SortedDict(dict):
-       def __repr__(self):
-           keys = sorted(self.keys())
-           result = ("{!r}: {!r}".format(k, self[k]) for k in keys)
-           return "{{{}}}".format(", ".join(result))
-
-       __str__ = __repr__
-
-This will work for many common situations you might encounter, though it's far
-from a perfect solution. The largest flaw is that if some values in the
-dictionary are also dictionaries, their values won't be presented in any
-particular order.

+Use :class:`collections.OrderedDict`.
