title: Get string instead of list in Pandas DataFrame
body: <p>I have a column <code>Name</code> of string data type. I want to get all the values except the last one and put it in a new column <code>FName</code>, which I could achieve</p>
  <pre><code>df = pd.DataFrame({'Name': ['John A Sether', 'Robert D Junior', 'Jonny S Rab'], 
                          'Age':[32, 34, 36]})
  df['FName'] = df['Name'].str.split(' ').str[0:-1]
  
                Name  Age        FName
  0    John A Sether   32    [John, A]
  1  Robert D Junior   34  [Robert, D]
  2      Jonny S Rab   36   [Jonny, S]
  </code></pre>
  <p>But the new column <code>FName</code> looks like a list, which I don't want. I want it to be like: <code>John A</code>.</p>
  <p>I tried convert the list to string, but it does not seems to be right.
  Any suggestion ?</p>
