title: Python dataframe : strip part of string, on each column row, if it is in specific format
body: <p>I have a column of values as such, on a Pandas DataFrame:</p>
  <pre><code>                column1
  
   google 5 8/10 07/08/74
              apple 4 1/5
         netflix 26/04/50
  facebook 5 1/4 17/10/40
  
  </code></pre>
  <p>My objective would be to remove the dates, on the rows where there are dates.</p>
  <p>What reasoning would you apply?</p>
  <p>Find if right side of value in each row is in format xx/xx/xx, and if so delete the 8 characters on the right? Would would Python recognize the xx/xx/xx format in part of the string?</p>
  <p>Thank you!</p>
