title: Python Pandas: Resample date range
body: <p>I create a list of pandas datetimes with the following line:</p>
  
  <pre><code>range = pd.date_range(start = '5/3/2005', periods =5+1, freq='1D')
  </code></pre>
  
  <p>Is there a quick way to resample that list so that it spans the same range but with a frequency of 30 min? (so far I can only see applications of that logic to Series or DataFrames index, but no daterange)</p>
