How do I run a Python script from a Photoshop script?

Question

Is it possible to run a run a Python script from a Photoshop script? For example: I've got two files: my_photoshop script.jsx which will run from Photoshop. And the seconds (python) my_python_script.py, which is called from with Photoshop by the first script.

my_photoshop script.jsx

// Call external file from Photoshop
call my_python_script.py; //pseudo code

my_python_script.py

# Python script
print ("Hello from Photoshop!")

I know it's possible to do something similar via a batch file...

my_photoshop script.jsx

// Call the external batch files
var myBat = new File("D:\\temp\\my_batch_file.bat");
alert(myBat);
myBat.execute();

my_batch_file.bat

echo Python...
"C:\path\to\python.exe" "c:\path\to\hello_world.py"
pause 100

However, but can it be done directly? Or is this as close as it's gonna get?

Using app.system:

my_script.jsx

app.system('python "D:/path/to/my_py.py" ' + app.version)

my_py.py:

import sys
file = open("D:/path/to/py.log", "w")
file.write("Hello from Photoshop!\n")
file.write("PS version: " + str(sys.argv[1]))
file.close()

Result of py.log:

Hello from Photoshop!
PS version: 20.0.10

p.s. note that File.execute() opens the file with a default app. If a user associated .bat files with a text editor, running myBat.execute() will open the file in the text editor.
