 We recommend to do initialization of the party only in the init() and not in the constructor or static code. 
 This because instances of your class can be made both for extracting general info as getDescription(), or to really run your class.

+= Writing a party in Python
+We provide a python-to-java adapter so that you can easily write your agent in python instead of Java. You can check the example code [https://tracinsy.ewi.tudelft.nl/trac/Genius2/browser/exampleparties/randompartypy here]. A python-based agent looks like this:
+{{{
+class RandomParty (DefaultParty):
+        def notifyChange(self, info):
+                if isinstance(info, Settings) :
+                        self._fetchProfile(info.getProfile())
+                        self.me = info.getID()
+                elif isinstance(info , ActionDone): 
+                        self.lastActor = info.getAction().getActor()
+                        otheract = info.getAction()
+                        if isinstance(otheract, Offer):
+                                self.lastReceivedBid = otheract.getBid()
+                elif isinstance(info , YourTurn):
+                        self._myTurn()
+
+        def getCapabilities(self): # -> Capabilities
+                return Capabilities(HashSet([ ProtocolRef(URI("SAOP"))]))
+
+        def getDescription(self):
+                return "places random bids until it can accept an offer with utility >0.6. Python version"
+        
+        def terminate(self):
+                self.profile.disconnect()
+
+        def _myTurn(self):
+                if self.lastReceivedBid != None and self.profile.getProfile().getUtility(self.lastReceivedBid).doubleValue() > 0.6:
+                        action = Accept(self.me, self.lastReceivedBid)
+                else:
+                        bidspace = AllBidsList(self._getProfile().getDomain())
+                        i = self.random.nextInt(bidspace.size()) # warning: jython implicitly converts BigInteger to long.
+                        action = Offer(self.me, bidspace.get(BigInteger.valueOf(i)))
+                self.getConnection().send(action)
+
+   ...
+}}}
+
+You need to wrap your python agent into a jar wrapper to get it accepted by the parties server. To do this, check the javadoc with the [https://tracinsy.ewi.tudelft.nl/trac/Genius2/browser/pythonadapter/src/main/java/genius2/pythonadapter/PythonPartyAdapter.java PythonPartyAdapter].
