title: Use same variable multiple times in print
body: <p>In Python if I want to use a variable in string while printing I do the following:</p>
  
  <pre><code>name = "newbie"
  site = "Stack Overflow"
  print("I, a %s, find %s very useful" % (name, site))
  </code></pre>
  
  <p>If I want to print <code>"I, a newbie, find Stack Overflow to be very very very useful'</code> and substitute <code>'very'</code> by a variable name, how can I do that, while still using the <code>name</code> and <code>site</code> variables?</p>
