title: Python Pandas Add empty column in the middle of a dataframe
body: <p>I am trying to add an empty column after the 3ed column on my data frame that contains 5 columns. Example:</p>
  <pre><code>Fname,Lname,city,state,zip
  
  mike,smith,new york,ny,11101
  </code></pre>
  <p>This is what I have and below I am going to show what I want it to look like.</p>
  <pre><code>Fname,Lname,new column,city,state,zip
  
  mike,smith,,new york,ny,11101
  </code></pre>
  <p>I dont want to populate that column with data all I want to do is add the extra column in the header and that data will have the blank column aka ',,'.
  Ive seen examples where a new column is added to the end of a data frame but not at a specific placement.</p>
