Drupal prevent unauthorized access -

how prevent unauthorized url access in drupal?

i tried 'access arguments' => array('access administration pages') didn't work

its given in drupal documentation on how use access arguments.this example per drupal documentation,just make more clear on how use this.

$items['test/mypage'] = array(     'title' => 'mypage',     'description' => 'welcome',     'page callback' => 'mypage_info',     'access arguments' => array('anyone can access this'),   );

//define user permissions.

function hook_perm() {         return array('anyone can access this'); }

now go permissions page [administer --> user management -->permissions), there can see list of strings used access arguments.you find access argument named 'anyone can access this' in corresponding module.give necessary permission required user roles.

you more information on following links

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...
