title: Python Converting Quarterly to Monthly Data
body: <pre><code>    0       1Q08
      1       2Q08
      2       3Q08
      3       4Q08
      4       1Q09
      5       2Q09
  </code></pre>
  
  <p>Currently My dataframe looks like this.
  I would love to convert the quaterly to monthly like this:</p>
  
  <pre><code>    0       01-01-08
      1       02-01-08
      2       03-01-08
      3       04-01-08
      4       05-01-08
      5       06-01-08
  </code></pre>
  
  <p>It requires adding two rows per each quarter and converting a quarter into three months. Is there a built-in function for this? If not, what would be an efficient way? Thanks!</p>
