title: Pandas index column title or name
body: <p>How do I get the index column name in python pandas?  Here's an example dataframe:</p>
  
  <pre><code>             Column 1
  Index Title          
  Apples              1
  Oranges             2
  Puppies             3
  Ducks               4  
  </code></pre>
  
  <p>What I'm trying to do is get/set the dataframe index title.  Here is what i tried:</p>
  
  <pre><code>import pandas as pd
  data = {'Column 1'     : [1., 2., 3., 4.],
          'Index Title'  : ["Apples", "Oranges", "Puppies", "Ducks"]}
  df = pd.DataFrame(data)
  df.index = df["Index Title"]
  del df["Index Title"]
  print df
  </code></pre>
  
  <p>Anyone know how to do this? </p>
