thank help!

you have ditch array_walk_recursive , roll own recursive walk. allow maintain or pass custom state information whenever recurse.

for example:

function my_walk_recursive(array $array, $path = null) {     foreach ($array $k => $v) {         if (!is_array($v)) {             // leaf node (file) -- print link             $fullpath = $path.$v;             // whatever want $fullpath, e.g.:             echo "link $fullpath\n";         }         else {             // directory node -- recurse             my_walk_recursive($v, $path.'/'.$k);         }     } }

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...
