Identifying keys by looking at values in a dictionary
<ul>
<li>I have a dictionary with key-value pairs like <code>{a : (b,c,d,e)}</code>.   </li>
<li>If i encounter a tuple <code>(b,c,d,e)</code>, i want to lookup in dictionary, the key having the same tuple as a value and delete that key from the dictionary. Can it be done like this in python?</li>
</ul>
