-

i have flash app in function have parse json passed object external api can't change.

my json this:

 {     "prodotti": [         {             "titolo": "test",             "marca": "",             "modello": "",             "cilindrata": "",             "potenza": "",             "alimentazione": "",             "images": {                 "img": [                     {                         "thumb": "admin/uploads/img_usato/small/qekabw95l5wh1alf6.jpg",                         "big": "admin/uploads/img_usato/big/qekabw95l5wh1alf6.jpg"                     },                     {                         "thumb": "admin/uploads/img_usato/small/default.jpg",                         "big": "admin/uploads/img_usato/big/default.jpg"                     }                 ]             }         },         {             "titolo": "motore volvo tamd 74 c",             "marca": "volvo penta",             "modello": "tamd 74 c",             "cilindrata": "7.283 cm3",             "potenza": "331 kw 2600 rpm",             "alimentazione": "gasolio",             "images": {                 "img": [                     {                         "thumb": "admin/uploads/img_usato/small/pmqwn4t4yp7p1ycwa.jpg",                         "big": "admin/uploads/img_usato/big/pmqwn4t4yp7p1ycwa.jpg"                     },                     {                         "thumb": "admin/uploads/img_usato/small/bwkjtgcy3pdm2lkrs.jpg",                         "big": "admin/uploads/img_usato/big/bwkjtgcy3pdm2lkrs.jpg"                     }                 ]             }         }     ] }

i want parse images inside object. api send me object not astring or json , have function now:

function changedata (prodotto:object) {     img_container.graphics.clear ();          //here want enter , take thumb , big of images!!!     (var index in prodotto.images.img) {         //trace('index: ' + index);         //trace("thumb: " + index.thumb + ' big: ' + index.big);     }          descrizione.htmltext = prodotto.testo_html;         titolo.text = prodotto.titolo;         alimentazione.text = prodotto.alimentazione;         potenza.text = prodotto.potenza;         cilindrata.text = prodotto.cilindrata;         modello.text = prodotto.modello;         marca.text = prodotto.marca;  }

the function works fine not for loop try take bug , thumb of json how can retrieve information in object?

thanks

i think there wrong how setting call since didn't show code api can't fix that, plus stated have no control on it. no matter issue not seem correct.

i put function thumbs , bigs. did not state otherwise.

function changedata (prodotto:object) {     each(var item in prodotto.prodotti){         trace('')         //trace(prodotto.testo_html);         trace(item.titolo);         trace(item.alimentazione);         trace(item.potenza);         trace(item.cilindrata);         trace(item.modello);         trace(item.marca);         each( var imgs in item.images.img) {             trace('thumb',imgs.thumb)             trace('big',imgs.big)         }     } }

i'm new python, question might easy, anyway, patience: as trying call newton-raphson method calculate implied volatility in black-scholes formula call/put option pricing, first thing is, newton method in scipy.optimize seems calculate function's zeros, in black-scholes formula, want function's value option price, not zero. (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...
