Most efficient way to create a dictionary of empty lists in Python?
<p>I am initializing a dictionary of empty lists. Is there a more efficient method of initializing the dictionary than the following?</p>

<pre><code>dictLists = {}
dictLists['xcg'] = []
dictLists['bsd'] = []
dictLists['ghf'] = []
dictLists['cda'] = []
...
</code></pre>

<p>Is there a way I do not have to write dictLists each time, or is this unavoidable?</p>
