title: Pandas adding blank column title with a count
body: <p>I am working on manipulating some csv's for my job. The code below works, it just has one minor issue. It is adding a column in front of the line "<code>df.insert(0,'ID',' ')</code>" with a blank column name and it is counting the number of rows. Is there any reason as to why this is happening? Please feel free to offer any insight or pick apart what I have as I am new to Python and I am sure this can be cleaned up or run more efficiently.</p>
  
  <p>Thanks,</p>
  
  <pre><code>import pandas as pd
  
  # Enter the full file path you want manipulated here
  print('Enter Filename Path')
  file = input()
  
  # Enter the report category you want added here. This needs to be exact
  print('Report Category')
  rcat = input()
  
  # Reads the CSV given above
  df = pd.read_csv(file)
  
  # This inserts the columns needed to fit the new VulnMan DB
  df.insert(0, 'ID', ' ')
  df.insert(4, 'Report Category', (rcat))
  df.insert(5, 'Status', 'Not Started ')
  df.insert(6, 'Comments', ' ')
  
  # Saves the file in the SAME NAME
  df.to_csv(file)
  </code></pre>
