How to run a python script (with modules)?

I'm using Namecheap's cPanel, and their support is terrible. I have a Laravel application that executes a python script that gives me the data I need. Currently, I'm using a a simple [CODE=php]$result = shell_exec("python filepath arg1 arg2 arg 3");
. I changed the python interpreter to the correct location, but the server doesn't have the correct modules to run the file. I was suggested to create a Python Web App, but I don't think that'll solve what I need, and that's just to run the python file and take the output of it. Does anyone have a better way of executing a python script(with modules) and take it's output?
