title: Map function and input function parameters
body: <p>Here's a stupid example:</p>
  
  <pre><code>def add_x_to_input(x,k):
     return x + k
  
  myList = [1,2,3,4]
  myNewList = map(add_x_to_input???, myList)
  </code></pre>
  
  <p>How do I specify the parameter <code>x</code> of <code>add_x_to_input</code>, when I give it as input function to <code>map</code>?</p>
