title: Update clock in program Python without creating new line
body: <p>I am creating a program for Raspberry Pi where, in Command Line, the program displays the date and time as shown below and I want to add a repeat or update so the date and time are current after the program begins. This code came off a online tutorial and I want to mess around with it and hit a dead end. I am currently learning Python.</p>
  
  <pre><code>#!/usr/bin/python
  
  import time
  now = time.strftime("%c")
  print "current date and time " + time.strftime("%c")
  </code></pre>
