Trying to condense my javascript (jquery) -

-

i'm relatively new javascript , jquery. rather using foundation or bootstrap i've decided roll , maintain own solution. i'm not worried individual components i've built of them before, responsive rows/columns bit of worry me.

this bit of code directly sets percentages col1-col-12 , mob1-mob12(12 columns, mob mobile only).

i have bit of css i'm playing goes hand in hand this. i'm relatively happy functionality of this, don't know how condense solutions further other datastructures or programmatic methods.

thanks in advance advice:

$(document).ready(function(){         var colelements = ".row, .col1, .col2, .col3, .col4, .col5, .col6, .col7, .col8, .col9, .col10, .col11, .col12";         var col1 = "8%";         var col2 = "16%";         var col3 = "25%";         var col4 = "33%";         var col5 = "41%";         var col6 = "50%";         var col7 = "58%";         var col8 = "66%";         var col9 = "75%";         var col10 = "83%";         var col11 = "91%";         var col12 = "100%";         function converttopercent(n){             var output = n.tostring();             output = output.concat("%");             return output         }         function responsiveadjust(){             $("body").find(colelements).each(function(){                 if($(this).hasclass("row")){                     $(this).width("100%");}                  if ($("body").width() > 499){                if($(this).hasclass("col1")){                     $(this).width(col1);

first of making things wrong. javascript not place such things. it's css should set sizes. that's because browser needs download javascript, evaluate , after render pages correctly. on mobile critical.

second, if still want things in javascript, should use this:

var sizes = {     col1: "8%",     col2: "16%",     col3: "25%",     col4: "33%",     col5: "41%",     col6: "50%",     col7: "58%",     col8: "66%",     col9: "75%",     col10: "83%",     col11: "91%",     col12: "100%",     row: "100%" }  for(var size in sizes) {     var el = $("." + size);     if(el.length > 0 && el.hasclass("mob11")){         el.width(sizes[size]);     }     }

just use arrays , interpolations. having bunch of if-else statements bad sign.

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...
