  Nope.  In Python maps (or "dictionaries") are un-ordered.  If order is
important to you, you'll need a different data structure, such as a list
(possibly in combination with a dictionary).

ground at the start and how much will be left at the end are unknown and
irrelevant."  -- Morry Adelman, World Renowned Economist
