Removing entries from a dictionary based on values
<p>I have a dictionary here with character - integer key value pair. I want to remove all those key value pairs where the value is 0.</p>

<hr>

<p>For example: Consider these</p>

<pre><code>&gt;&gt;&gt; hand
{'a': 0, 'i': 0, 'm': 1, 'l': 1, 'q': 0, 'u': 0}
</code></pre>

<p>And I want to reduce the same dictionary to this</p>

<pre><code>&gt;&gt;&gt; hand
{'m': 1, 'l': 1}
</code></pre>

<hr>

<p>Is there an easy way to do that ?</p>
