title: "For" loop first iteration
body: <p>I would like to inquire if there is an elegant pythonic way of executing some function on the first loop iteration.
  The only possibility I can think of is:</p>
  
  <pre><code>first = True
  for member in something.get():
      if first:
          root.copy(member)
          first = False
      else:
          somewhereElse.copy(member)
      foo(member)
  </code></pre>
