title: Split a list into sublists based on certain string
body: <p>I am pretty new to python, so my question is:</p>
  
  <p>I have a list like this:</p>
  
  <pre><code>L = ['Name1', 'String1', 'String2', 'String3', 'Name2', 'String4', 'String5', 'String6', ...]
  </code></pre>
  
  <p>I would like to convert it into a new list in which all the strings after a certain 'name' are in a sub-list with the name like:</p>
  
  <pre><code>L2 = [['Name1', 'String1', 'String2', 'String3'],['Name2', 'String4', 'String5', 'String6'],[...]]
  </code></pre>
  
  <p>Whats the best way to do that?</p>
