python - How can php-files find namespaces in other php-files? -

-

coming python i'm trying make sense of way php uses namespaces. in python import follows:

import somemodule anothermodule import someclass

this works charm , expect.

in php on other hand, we've got namespaces. far understand can define namespace on top of mymodule.php this:

namespace mynamespace;

if i'm correct means code in file can referred (or imported by) name "mynamespace" in myworkingcode.php doing this:

use mynamespace;

so question; how myworkingcode.php find mymodule.php? need in same folder work or need else?

the use function in php completly different import in python.

use there creating aliases long namespaces. example:

use \my\very\long\omg\its\sooooo\long\how\stupid veryshort;

now every class inside long namespace available under namespace veryshort. more info: http://php.net/manual/en/language.namespaces.importing.php

then, how php find correct file? doesn't. have include yourself, if use strong naming convention files can use autoloaders spl_autoload_register function. standard can found here: http://www.php-fig.org/psr/0/

python - TypeError: can only concatenate tuple (not "float") to tuple -

-
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...
