title: What's a convenience function?
body: <p>In the timeit module there is the code below - what's a convenience function? I googled it and couldn't find a good answer:</p>
  
  <pre><code>def timeit(stmt="pass", setup="pass", timer=default_timer,
             number=default_number, globals=None):
      """Convenience function to create Timer object and call timeit method."""
      return Timer(stmt, setup, timer, globals).timeit(number)
  </code></pre>
