title: use random functions (python)
body: <p>I wonder if we can do that in python, let's suppose we have  3 differents functions to processing datas
  like this:</p>
  
  <pre><code>def main():
    def process(data):
       .....
    def process1(data):
       .....
    def process2(data):
       .....
    def run():
       test = choice([process,process1,process2])
       test(data)
    run()
  
  main()
  </code></pre>
  
  <p>Can we choice one random function to process the data ?
  If yes, is this a good way to do so ?</p>
  
  <p>Thanks !</p>
