-

please tell me how retrieve sid , jid. using strophe js.

<body rid='489923353' xmlns='http://jabber.org/protocol/httpbind' sid='ab7f5957' to='127.0.0.1' xml:lang='en' xmpp:restart='true' xmlns:xmpp='urn:xmpp:xbosh'/>  var conn = new strophe.connection(bosh_service);

however, conn.sid or conn.rid not returning same numbers.

after , that, think found answer! 

else if(status === strophe.status.connected){          //get roster         var iq = $iq({type: 'get'}).c('query', {xmlns: 'jabber:iq:roster'});         chat.connection.sendiq(iq, chat.on_roster);           //on chat         chat.connection.addhandler(chat.on_message,null, "message", "chat");          $("#presence").html("connection sid" + chat.connection.sid + "connection rid" +  chat.connection.rid);     }

(i'm new here programming, i'm not sure techniques.) should write function things like: def f(sigma, price): return bsformula(s0,k,r,t,q,sigma) - price then, while calling newton method, takes args=() 1 parameter in function, write this: value = newton(bsprice2, 0.5, args=price) but error message: file "bs.py", line 36, in bsimpvol value = newton(bsprice2, 0.5, args=float(price)) file "/usr/lib/python2.7/dist-packages/scipy/optimize/zeros.py", line 143, in newton q0 = func(*((p0,) + args)) typeerror: can concatenate tuple (not "float") tuple could tell me why that? how fix it? apprecia...
