python - extracting values from dictionary in order
<p>I have a dictionary with some share related data:</p>

<pre><code>share_data = {'2016-06-13':{'open': 2190, 'close':2200}, '2015-09-10':{'open': 2870, 'close':2450} # and so on, circa 1,500 entries
</code></pre>

<p>is there a way of iterating over the dictionary in order, so the oldest date is retrieved first, then the one soon after etc?</p>

<p>thanks!</p>
