title: How to show elements of a list
body: <p>I've got a simple question and I'm sure you can solve it:</p>
  
  <p>How can I show the elements of a list?</p>
  
  <p>If I have a list LIST of (named) elements, how do I know which elements are within this list without typing in "LIST"?</p>
  
  <p>There must be a simple command like str(LIST), but I can't find it...</p>
  
  <p>Thanks in advance</p>
