title: Can you use loc to select a range of columns plus a column outside of the range?
body: <p>Suppose I want to select a range of columns from a dataframe: Call them 'column_1' through 'column_60'. I know I could use loc like this:
  <code>df.loc[:, 'column_1':'column_60']</code>
  That will give me all rows in columns 1-60. </p>
  
  <p>But what if I wanted that range of columns plus 'column_81'. This <i>doesn't</i> work:
  <code>df.loc[:, 'column_1':'column_60', 'column_81']</code></p>
  
  <p>It throws a "Too many indexers" error. 
  Is there another way to state this using loc? Or is loc even the best function to use in this case? </p>
  
  <p>Many thanks.</p>
