title: Selecting a subset of functions from a list of functions in python
body: <p>I have a list: <code>mylist = [1,2,5,4,7,8]</code>
  I have defined a number of functions that operate on this list. For example:</p>
  
  <pre><code>def mean(x): ...
  def std(x): ...
  def var(x): ...
  def fxn4(x): ...
  def fxn5(x): ...
  def fxn6(x): ...
  def fxn7(x): ...
  </code></pre>
  
  <p>Now I am given a list of function names that I want to apply on mylist.</p>
  
  <p>for ex:  <code>fxnOfInterest = ['mean', 'std', 'var', 'fxn6']</code></p>
  
  <p>What is the most pythonic way to call these function?</p>
