title: Python - Get Last Element after str.split()
body: <p>I use pandas and I have data and the data look like this</p>
  <pre><code>FirstName LastName StudentID
  FirstName2 LastName2 StudentID2
  </code></pre>
  <p>Then I split it based on 'space' using <code>str.split()</code></p>
  <p>So the data will look like this in DataFrame</p>
  <pre><code>[[FirstName, LastName, StudentID],
  [FirstName2, LastName2, StudentID2]]
  </code></pre>
  <p>How to take the StudentID for every students only and save it in new column?</p>
