title: Python split string on regex
body: <p>I'm trying to split a string using a regular expression.  </p>
  
  <pre><code>Friday 1Friday 11 JAN 11
  </code></pre>
  
  <p>The output I want to achieve is </p>
  
  <pre><code>['Friday 1', 'Friday 11', ' JAN 11']
  </code></pre>
  
  <p>My snippet so far is not producing the desired results:</p>
  
  <pre><code>&gt;&gt;&gt; import re
  &gt;&gt;&gt; p = re.compile(r'(Sunday|Monday|Tuesday|Wednesday|Thursday|Friday|Saturday)\s*\d{1,2}')
  &gt;&gt;&gt; filter(None, p.split('Friday 1Friday 11 JAN 11'))
  ['Friday', 'Friday', ' JAN 11']
  </code></pre>
  
  <p>What am I doing wrong with my regex?</p>
