title: Python getting the last part after spliting with a dot
body: <pre><code>la = ["a.b.c.d", "a.b.c", "y.d.k", "z"]
  a = []
  for i in la:
      j = i.split('.')
      a.append(j[-1])
  print a
  </code></pre>
  
  <p>shows d, c, k, z</p>
  
  <p>I feel like getting <code>a</code> (a list of last part after dot from la) can be done in an one-liner. anyone have a better solution to this?</p>
