Alternatively, you can decide to not care, and to present the dictionary keys 
in some arbitrary order of your chosing when printing output (commonest example 
is probably lexically sorted).

On the other hand, if you really do want the insertion order then OrderedDict 
is the way to do, as several others have mentioned.
