title: Unpack tuple in a string literal?
body: <p>Here is a code:</p>
  
  <pre><code>a = 'a b c'
  b = 'd'
  
  def func(a):
      a_list = a.split(' ')
      return a_list[0], a_list[1], a_list[2]
  
  
  print '1 = %s, 2 = %s, 3 = %s, 4 = %s' % (func(a), b)
  
  (func(a), b)
  </code></pre>
  
  <p>gives an error.</p>
  
  <p>I tried </p>
  
  <pre><code>(*(func(a)), b)
  </code></pre>
  
  <p>with no luck.</p>
