title: Change Tor IP from Python with Stem
body: <p>Specs (MacOSx - Last version , Python 3.5 , Stem and Tor Browser for Mac)</p>
  
  <p>I just start to learn more about Tor and i wanted to change my Tor route from Python Script.</p>
  
  <pre><code>from stem import Signal
  from stem.control import Controller
  from stem import CircStatus
  
  def getIP():
      with Controller.from_port(port = 9151) as controller:
          controller.authenticate()
          for circ in controller.get_circuits():
              if circ.status != CircStatus.BUILT:
                  continue
  
              exit_fp, exit_nickname = circ.path[-1]
  
              exit_desc = controller.get_network_status(exit_fp, None)
              exit_address = exit_desc.address if exit_desc else 'unknown'
  
              print ("Exit relay")
              print ("  fingerprint: %s" % exit_fp)
              print ("  nickname: %s" % exit_nickname)
              print ("  address: %s" % exit_address)
  
  def newIP():
      with Controller.from_port(port = 9151) as controller:
          controller.authenticate()
          controller.signal(Signal.NEWNYM)
          print("\n\nNEW IP, NEW IP\n\n")
  
  getIP()
  newIP()
  getIP()
  </code></pre>
  
  <p>But the above code doesn't negociate a new ip between the two getIP().
  I checked that the connection was right :</p>
  
  <pre><code>telnet localhost 9151
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  </code></pre>
  
  <p>Could you help me to understand why can't i do it ?</p>
  
  <p>Regards,</p>
  
  <p>Jérémy.</p>
