Greetings! I use IIS to run my localhost. I have a form on the website where a user enters some data, then PHP gets these data and should run Python script. To run it I try to use following commands:

<?php

shell_exec("python script_folder/test.py");

?>

and 

<?php

exec("python script_folder/test.py");

?>

but nothing happens. Python script is trivial:

import time  

print("It works!")

time.sleep(3)

I guess there is an issue with permissions. Possibly a user that connects website doesn't have privilege to use cmd.

Could you please help how to proceed?
