title: Tokenize by using regular expressions (parenthesis)
body: <p>I have the following text:</p>
  
  <p><code>I don't like to eat Cici's food (it is true)</code> </p>
  
  <p>I need to tokenize it to </p>
  
  <p><code>['i', 'don't', 'like', 'to', 'eat', 'Cici's', 'food', '(', 'it', 'is', 'true', ')']</code> </p>
  
  <p>I have found out that the following regex expression <code>(['()\w]+|\.)</code> splits like this:</p>
  
  <p><code>['i', 'don't', 'like', 'to', 'eat', 'Cici's', 'food', '(it', 'is', 'true)']</code> </p>
  
  <p>How do I take the parenthesis out of the token and make it to an own token?</p>
  
  <p>Thanks for ideas.</p>
