title: How to convert a list of tuples into a single string
body: <p>I have a list of tuples, where all emlements in the tuples are strings. It could look like this:</p>
  
  <pre><code>my_list = [('a', 'b', 'c'), ('d', 'e')]
  </code></pre>
  
  <p>I want to convert this to a string so it would look like 'a b c d e'. I can use ' '.join( ... ) but I'm unsure of what argument I should use. </p>
