title: Pandas parsing csv error - expected 1 fields found 9
body: <p>I'm trying to parse from a .csv file:</p>
  
  <pre><code>planets = pd.read_csv("planets.csv", sep=',')
  </code></pre>
  
  <p>But I always end up with this error:</p>
  
  <pre><code>ParserError: Error tokenizing data. C error: Expected 1 fields in line 13, saw 9
  </code></pre>
  
  <p>This is how the first few lines of my csv file look like:</p>
  
  <pre><code># This file was produced by the test

  # COLUMN pl_hostname:    Host Name
  # COLUMN pl_discmethod:  Discovery Method

  <p><strong>Edit:</strong> this is line 13:</p>

  </code></pre>
  
  <p><strong>Edit:</strong> Thanks to @Rakesh, Skipping the first 12 lines solved the problem</p>
  
  <p>planets = pd.read_csv("planets.csv", sep=',', skiprows=12)</p>
