title: Writing Python lists to columns in csv
body: <p>I have 5 lists, all of the same length, and I'd like to write them to 5 columns in a CSV. So far, I can only write one to a column with this code:</p>
  
  <pre><code>with open('test.csv', 'wb') as f:
      writer = csv.writer(f)
      for val in test_list:
          writer.writerow([val])
  </code></pre>
  
  <p>If I add another <code>for</code> loop, it just writes that list to the same column. Anyone know a good way to get five separate columns?</p>
