<div id="output">     <form id="suserb" name="output" action="" method="post">         <input type="submit" value="select" name="suser"></form>     <div id="suser">         <?php         if (isset($_post['suser'])) {             $omysql = new mysql('library', 'root', '', 'localhost');             $where = array('bid' => '0');             echo "<pre>";             $result = $omysql->select('user', $where);             print_r($result);             echo "</pre>";             foreach ($result $key => $val) {                 foreach ($val $label => $item) {                     echo $label . "====" . $item . "<br >";                 }             }         }         ?>     </div>

regards

isn't obvious result stays on page? every time refresh page, query gets executed , spits out content of table on page.

(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...
