Remove space from dictionary keys
<p>I have a dictionary with keys/values such as:</p>

<pre><code>{'C  14': ['15263808', '13210478'], 'W   1': ['13122205']}
</code></pre>

<p>How can I remove the white space from all of the keys so they instead would be:</p>

<pre><code>{'C14': ['15263808', '13210478'], 'W1': ['13122205']}
</code></pre>
