copied!<p>(1) You don't actually define <code>word_count</code> in <code>dict_creator</code>. I was expecting to see</p> <pre><code>word_count = {} </code></pre> <p>at the start. This means that whatever <code>word_count</code> it's changing is defined elsewhere and global, so whenever you call <code>dict_creator</code> it'll add to the same <code>word_count</code> dictionary, increasing the values. You only ever have one <code>word_count</code>, at least from the code you've shown.</p> <p>(2) As for the KeyError:</p> <pre><code> for word in sorted(word_count.iteritems(), key=operator.itemgetter(1), reverse=True): #create sorted list of tuples using operator module functions sorted in an inverse manner a = word b = word_count[word] </code></pre> <p><code>iteritems()</code> returns the tuples, so <code>word</code> is already something like <code>('dict_creator', 1)</code>. You can simply print it as it is. Calling <code>word_count[word]</code> tries to use the tuple of <code>(key, value)</code> as the key. IOW, even though you've called the variable word, it's really <code>word_and_count</code>, with <code>word, count = word_and_count</code>.</p> <p>(3) In this part:</p> <pre><code> return word_count #return word_count dictionary word_count.close() </code></pre> <p>I think you mean <code>input_file.close()</code>, but there's no point in closing the file "after" you return, because that line won't be executed. Another option is to use the <code>with</code> idiom:</p> <pre><code>with open(filename) as input_file: code_goes_here = True return word_count </code></pre> <p>here the file will automatically be closed.</p> <p>After making the above changes, your code seems to work for me.</p>
