title: How to format existing data into columns on csv file in python 3.5
body: <p>I have a csv file with data in each row separated with space. I want to format these datas in columns. So if I have 5 values separated by space in a row then I want to create 5 columns. My csv file looks like following,
  <a href="https://i.stack.imgur.com/tOblF.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/tOblF.jpg" alt="enter image description here"></a></p>
  
  <p>I want to format them on 7 columns. I'm using pandas and trying to set the column like this</p>
  
  <pre><code>dataFrame.columns= ['Frame',  'xmin', 'xmax', 'ymin','ymax', 'occluded', 'Label']
  </code></pre>
  
  <p>But its showing me an error</p>
  
  <blockquote>
    <p>ValueError: Length mismatch: Expected axis has 1 elements, new values
    have 7 elements</p>
  </blockquote>
