title: Is it possible for a statement to be executed after raise in python?
body: <p>I found following code in <a href="http://twistedsnmp.sourceforge.net/" rel="noreferrer">TwistedSNMP</a> library:</p>
  
  <pre><code>try:
    raise ImportError
    import psyco
  except ImportError, err:
    pass
  else:
    from pysnmp.asn1 import base
    psyco.bind(base.SimpleAsn1Object)  psyco.bind(base.Asn1Object)
  </code></pre>
  
  <p>Source filename: <a href="http://twistedsnmp.cvs.sourceforge.net/viewvc/twistedsnmp/twistedsnmp/pysnmpproto.py?view=markup" rel="noreferrer">pysnmpproto.py, Line 42</a></p>
  
  <p>Are there any cases that either <code>import psyco</code> or <code>else</code> block will ever be executed?</p>
