title: Python cut a string after Xth sentence
body: <p>I have to cut a <strong>unicode</strong> string which is actually an article (contains sentences) I want to cut this article string after Xth sentence in python.</p>
  
  <p>A good indicator of a sentence ending is that it ends with full stop (".") and the word after start with capital name. Such as</p>
  
  <pre><code>myarticle == "Hi, this is my first sentence. And this is my second. Yet this is my third."
  </code></pre>
  
  <p>How can this be achieved ?</p>
  
  <p>Thanks</p>
