title: Write multiple values in a csv cell without brackets in python
body: <p>I have a list of objects. Each object have different attributes.
  One of which is a list
  I would like to export this objects to a csv file that looks like</p>
  
  <pre><code>a, "1,2,3"
  b,"1,2,3"
  </code></pre>
  
  <p>so that the csv is readable in a Excel program</p>
  
  <p>My code looks something like this:</p>
  
  <pre><code>final_list = []
  for a in list:
          first_value = a.first_value
          list2 = []
          for b in a.list:
              list2.append(b)
  
          final_list.append(first_value)
          final_list.append(list2)
  with open('file' ) as f:
          writer = csv.writer(f)
          writer.writerows(final_list)
      pass           
  </code></pre>
  
  <p>which results in this csv rows with the brackets and quotes that i don't want</p>
  
  <pre><code>1, "['1','3','4']"
  2,"['1','2','3']"
  </code></pre>
  
  <p>I need 2 values per row: <code>a</code> and <code>1,2,3</code> as string</p>
