Run python script with file and user e-mail

Hello!

I have an issue similar to this one.

Im trying to run a python script that takes the uploaded file and the user’s e-mail as input.

if (!function_exists('wfu_after_upload_handler')) {
	function wfu_after_upload_handler($changable_data, $additional_data) {
		$files = $additional_data["files"];
		$result = "";
		foreach ( $files as $file )
			if ( $file["upload_result"] == "success" || $file["upload_result"] == "warning" ) {
				$file_path = $file["filepath"];
				exec('python path/to/script.py', $result, $return_var);;
				break;
			}
		if ( $result != "" )
			foreach ($result as $line) {
       			$changable_data["js_script"] = 'console.log("'.$line.'");';
  			}
		return $changable_data;
	}
	add_filter('wfu_after_upload', 'wfu_after_upload_handler', 10, 2);
}

For now, the script is a simple helloworld just for testing, but I’ve been unable to make it work. I’m new to php and WordPress so my questions may be a bit silly, but here they are:

1) Is path/to/script.py relative to wp-content?

2) Eventually I’ll need to get the logged user’s email (or some kind of user data). I assumed it should be somewhere in ‘$additional_data[user-data]’. I tried using this

console.log("'.$additional_data["user_data"].'");

to take a look inside ‘user_data’ but I’m sure I’m doing something wrong, since it’s not working.

I’m using the free version of the plugin.

Thanks in advance! Any help will be greatly appreciated!
