Answer 1

from here , shell_exec is disabled when PHP is running in safe mode .

but you can try this,

<?php
    $result;
    $resultD;
    $arg= $ord." ".$time2_int;


    $command = escapeshellcmd('python3 path/to/python_file/decemberlist.py '.$arg);
    $result= shell_exec($command);


    $resultD=json_decode($result,true);
    echo $resultD['song'];
 ?>
