title: Converting date formats in pandas dataframe
body: <p>I have a dataframe and the Date column has two different types of date formats going on.</p>
  
  <p><code>eg. 1983-11-10 00:00:00 and 10/11/1983</code></p>
  
  <p>I want them all to be the same type, how can I iterate through the Date column of my dataframe and convert the dates to one format?</p>
