Passing the result of a python script to an ExtendScript `.jsx` file

So, I'm writing a python script that gets data from a google sheet and returns it back to an ExtendScript script that I'm writing for After Effects.

The relevant bits are :

getSpreadsheetData.py

def main():
    values = getSpreadsheetRange("1M337m3YHCdCDcVyS4fITvAGJsw7rGQ2XGbZaKIdkJPc", "A1:Q41")
    return processValues(values)

afterEffectsScript.jsx

var script_file = File("getSpreadsheetData.py");
var results = script_file.execute();
$.writeln(results);
alert("done!");

So, I have three questions :

How do I pass variables from the afterEffectsScript.jsx to the python script (for example the spreadsheet id and range)?
How do I get a return from the python script and return it back to the jsx file?
How do I make my afterEffectsScript to work async so that it can wait for the python script to get what it needs...

Thanks in advance for the advice!

After Effects has the possibility to call system commands and get the result of stdout.

var cmd = "pwd";
var stdout = system.callSystem(cmd);
$.writeln(stdout);

Take a look into the AE Scripting Guide

You can pass variables via setting environment variables. Small example how call external script with args from extendscript:

var script_file = File("getSpreadsheetData.py");
$.setenv("arg_1", "arg1_value");
$.setenv("arg_2", "arg2_value");
script_file.execute();

You python script should start with reading this varibles from environment: Access environment variables from Python
