title: Join a list of strings such that each string is within quotes and comma separated
body: <p>Consider that I have a list of customer names:</p>
  
  <pre><code>lst = ['John','Jack','Martin']
  </code></pre>
  
  <p>The desired output in a variable: <code>'John','Jack','Martin'</code></p>
  
  <p>I can use something like <code>",".join(lst)</code> and then more string formatting to achieve this. Is there any clear and more direct approach to this?</p>
  
  <p>My idea is to pass the elements of a string in a SQL <code>where</code> clause.</p>
