title: Access the index of a pandas series
body: <p>I am trying to identify which word is the most counted in a pandas dataframe (df_temp in my code). Also I have this :</p>
  <pre><code> l = df_temp['word'].count_values()
  </code></pre>
  <p>l is then obviously a pandas series where the first row points toward the most counted index (in my case the most counted word) in df_temp['word']. Although I can see the word in my console, I cannot get it properly. The only way I found so far is to transform it into a dictionary so I have :</p>
  <pre><code>dl = dict(l)
  </code></pre>
  <p>and then I can easily retrieve my index...after sorting the dictionary. Obviously this does the job, but I am pretty sure you have a smarter solution as this one is very dirty and inelegant.</p>
