    echo $nick;//prints ozan to webpage
  $res = shell_exec("C:\Python27\python.exe C:\wamp\www\MLWebsite\website\new.py '".$nick."'");

#!c:/Python27/python.exe
print("Content-Type: text/html")
print("""

No I can print $nick in php file. I tried that. @Jean-FrançoisFabre — ozan, Dec 26 '17 at 20:04
Have you tried just printing `sys.argv` and seeing what's in it? — ubadub, Dec 26 '17 at 20:07
I try that after you said. The result is that `'C:\\wamp\\www\\MLWebsite\\website\\new.py']` @ubadub — ozan, Dec 26 '17 at 20:08
Yea, that means `$nick` is definitely empty. Can you try `echo`ing `$nick$ in the PHP just to make sure? — ubadub, Dec 26 '17 at 20:11
Open windows cmd and paste ```C:\Python27\python.exe C:\wamp\www\MLWebsite\website\new.py 'test'``` — Wolen, Dec 26 '17 at 20:13
WhenI write echo `$nick` to php, I see my nickname in webpage. It is not empty in php file but I cannot pass it to python I think. @ubadub — ozan, Dec 26 '17 at 20:13

I try but `sys.argv` is always equal to `['C:\\wamp\\www\\MLWebsite\\website\\new.py']` @ubadub — ozan, Dec 26 '17 at 20:21
@ozan see the question I linked to. Your question is a duplicate. — ubadub, Dec 26 '17 at 20:22
Should I install any python package? Or I am using local WAMP SERVER and Is it possible because of that? — ozan, Dec 26 '17 at 20:26

This should do it

$res = shell_exec('C:\Python27\python.exe C:\wamp\www\MLWebsite\website\new.py ' . $nick);
