How do I list occurrences of certian values found in a dictionary in a list in python?
<pre><code>dave = [{'date':'12/10/12','time':'09:12','created_by':'adam','text':'this'},
        {'date':'28/09/11','time':'15:58','created_by':'admin','text':'that'},
        {'date':'03/01/10','time':'12:34','created_by':'admin','text':'this and that'}]
</code></pre>
