title: Get row-index values of Pandas DataFrame as list?
body: <p>I'm probably using poor search terms when trying to find this answer. Right now, before indexing a DataFrame, I'm getting a list of values in a column this way...</p>
  
  <pre><code> list = list(df['column']) 
  </code></pre>
  
  <p>...then I'll <code>set_index</code> on the column. This seems like a wasted step. When trying the above on an index, I get a key error.</p>
  
  <p>How can I grab the values in an index (both single and multi) and put them in a list or a list of tuples?</p>
