title: Python: How to split a string column in a dataframe?
body: <p>I have a dataframe with two columns one is <code>Date</code> and the other one is <code>Location(Object)</code> datatype, below is the format of Location columns with values :</p>
  
  <pre><code> Date                                            Location
  1     07/12/1912                            AtlantiCity, New Jersey   
  2     08/06/1913                 Victoria, British Columbia, Canada   
  3     09/09/1913                                 Over the North Sea   
  4     10/17/1913                         Near Johannisthal, Germany   
  5     03/05/1915                                    Tienen, Belgium   
  6     09/03/1915                              Off Cuxhaven, Germany   
  7     07/28/1916                              Near Jambol, Bulgeria   
  8     09/24/1916                                Billericay, England   
  9     10/01/1916                               Potters Bar, England   
  10    11/21/1916                                     Mainz, Germany
  </code></pre>
  
  <p>my requirement is to split the Location by <code>","</code> separator and keep only the second part of it <code>(ex. New Jersey, Canada, Germany, England etc..)</code> in the Location column. I also have to check if its only a single element (values with single element having no ",")</p>
  
  <p>Is there a way I can do it with predefined method without looping each and every row ?</p>
  
  <p>Sorry if the question is off the standard as I am new to Python and still learning.</p>
