php - Reorder the sequence of records in mysql -

-

how rearrange multiple records after deleting multiple records.my code deletes 1 record , rearrange records when delete multiple records,it cant reshuffle.

this codes works great when delete 1 record not work multiple records,

$sql="delete $user id='$id'"; $result=mysql_query($sql,$connection) or die(mysql_error());  $reorder = "update $user set id=id-1 id > $id"; $catch = mysql_query($reorder,$connection);

you may need query for rows require reorder, re-order them calling update statement 1 @ time, careful set id='xx-1' id='xx'

(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...
