Using a range as a dictionary index in Python
<p>Is it possible to do something like:</p>

<pre><code>r = {range(0, 100): 'foo', range(100, 200): 'bar'}

print r[42]

&gt; 'foo'
</code></pre>

<p>So I would like to use a numeric range as part of a dictionary index. To make things more complicated I would also like to use multi-indexes like <code>('a', range(0,100))</code>. So the concept should be ideally expandable to that. Any suggestions?</p>

<p>A similar question was asked as <a href="https://stackoverflow.com/q/13464143/2075003">here</a>, but I am interested in a comprehensive implementation as opposed to the different approaches of that question.</p>
