title: Python looping when there is only one item in the list
body: <p>Hello i need to loop over a few accounts but sometimes there is only one account. What is the best way to do that please?</p>

  <pre><code>accounts = ('X123456','Y325252')
  for account in accounts:
      do stuff
  </code></pre>
