title: Why "try...else" is "invalid syntax" in Python?
body: <p>normal:</p>
  
  <pre><code>try:
      something may go wrong...
  except:
      pass
  else:
      others func...
  </code></pre>
  
  <p>what i need:</p>
  
  <pre><code>try:
      something may go wrong...
  else:
      others func...
  </code></pre>
  
  <p>Are there some reasons for 'try...else' not exists?</p>
