body: <p>Here is my df:</p>
  
  <pre><code>                             Net   Upper   Lower  Mid  Zsore
  Answer option                                                
  More than once a day          0%   0.22%  -0.12%   2    65 
  Once a day                    0%   0.32%  -0.19%   3    45
  Several times a week          2%   2.45%   1.10%   4    78

  <p>How can I move a column by name (<code>"Mid"</code>) to the front of the table, index 0. This is what the result should look like:</p>
  
  <pre><code>                             Mid   Upper   Lower  Net  Zsore
  Answer option                                                
  More than once a day          2   0.22%  -0.12%   0%    65 
  Once a day                    3   0.32%  -0.19%   0%    45
  Several times a week          4   2.45%   1.10%   2%    78
  Once a week                   6   1.63%  -0.40%   1%    65
  </code></pre>
  
  <p>My current code moves the column by index using <code>df.columns.tolist()</code> but I'd like to shift it by name. </p>
