Python counting item's appearences in list
<p>Given</p>

<pre><code>listEx = ['cat', 'dog', 'cat', 'turtle', 'apple', 'bird', 'bird']

for i in listEx:
    if listEx.count(i) &gt; 1:
        print "this item appears more than once", i
    else:
        print "this item appears only once", i
</code></pre>

<p>I want it to print that cat and bird appear more than once (or just produce <code>['cat', 'bird']</code>). How can I do this?</p>
