title: Separate columns in csv Python
body: <p>I have a CSV file with the following columns:</p>
  
  <pre><code>"Advertising, Marketing, Promotions, Public Relations, and Sales Managers"
  </code></pre>
  
  <p>I am trying to separate those strings with delimiter in python. Following is my code so far:</p>
  
  <pre><code>with open('output-onlinecsvtools.csv', 'r') as f:
  reader = csv.reader(f, delimiter=',')
  </code></pre>
  
  <p>However, this only does the job for the first comma and also creates a duplicate. I am not concerned about the duplicates as I can remove them but I thought delimiter works for as many commas as they are in the cell.</p>
