title: map lambda x,y with a constant x
body: <p>What would be an elegant way to <code>map</code> a two parameter <code>lambda</code> function to a list of values where the first parameter is constant and the second is taken from a <code>list</code>?</p>
  
  <p><strong>Example:</strong></p>
  
  <pre><code>lambda x,y: x+y
  x='a'
  y=['2','4','8','16']
  </code></pre>
  
  <p>expected result:</p>
  
  <pre><code>['a2','a4','a8','a16']
  </code></pre>
  
  <p>Notes:</p>
  
  <ul>
  <li>This is just an example, the actual lambda function is more complicated</li>
  <li>Assume I can't use list comprehension</li>
  </ul>
