title: Text cleaning: removing dates from text, where there are
body: <p>I would need to clean some text which may contain a sequence like this:</p>
  <pre><code>Date            Text
  2020-06-01  1 giu 2020 - Per farlo hai messo in atto un pia...
  2020-06-01  La trappola del Paragone
  2020-06-05  5 giu 2020 - sistema Aegis Ashore? N...
  2020-06-05  Lewis Hamilton - «Il silenzio colpevole della F1»
    
  </code></pre>
  <p>There might be texts which starts with a date (format <code>1 giu 2020</code>, i.e. d m yyyy, followed by <code>-</code>) and texts which do not.
  I would like to know how to keep only the part of text, i.e.</p>
  <pre><code>Date            Text
  2020-06-01  Per farlo hai messo in atto un pia...

  <p>I have tried as follows:</p>
  <p><code>fil_dataset['Text']=fil_dataset['Text'].str.split(n=4).str[-1]</code>  but does not work as it can remove also part of text. A possible solution, proposed by anky in his/her comment below, unfortunately does not work as well, as I need also to keep in mind that there might be a <code>-</code>, which does not follow a date, that could remove some text.</p>
  <p>Thank you for your help.</p>
