php - "Cannot redeclare class" issue in FuelPHP -

-

working namespaces in default fuelphp installation add following welcome controller (otherwise unedited) , start getting error:

errorexception [ compile error ]: cannot redeclare class fuel\controller\welcome"

the code is: 

<?php  namespace fuel\controller;  use fuel\core\controller;   class welcome extends controller { ... }

this beginner's question can't figure out why collision occurring , have tried can think of.

edit: tried putting following code in front of class , error disappeared generic looking 404 page displayed. (not 1 displayed default fuelphp black/grey one)

if (class_exists("controller\welcome",false)) { //    echo "here. (" . __file__ . ":" . __line__ . ")\n";  } else {     //class definition...  }

the answer turned out have change controller prefix in config file following: 

  'controller_prefix' => 'controller\\',

which written in documentation. (silly me)

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...
