var v_url = 'getbiddingrows.jsp'; store:  ext.create('ext.data.store', {                 fields:[                 {name: 'stat_data', type: 'date' , sorttype: 'asdate', format: 'y-m-d h:m:s'},                 {name: 'operator_desc'},                 {name: 'vendor_name'},                 {name: 'currency'},                 {name: 'rate', type: 'float', sorttype: 'asfloat'}                 ],                 proxy: {                     type: 'ajax',                     timeout: 120000,                     url: v_url,                     reader: {                         type: 'json',                         root: 'data',                         successproperty: 'success'                     }                 },                 autoload: true             }),

how pass var temp getbiddingrows.jsp?

you can send server using ajax request:

ext.ajax.request({     url: 'foo',     params: {         vendors: temp     } });

(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...
