Running AppleScripts from Python

applescript_run.py

import subprocess

def applescript_to_list (file, path="/my/default/path/"):
    # open an applescript and return its contents as a list
    applescript = open(path + file + ".applescript", "r")
    lines = applescript.readlines()
    applescript.close()
    return lines

def applescript_list_to_string (script_list):
    # take a list of applestring commands and return it as a single string
    return ''.join(script_list)

def applescript_string_to_args (script_string):
    # take an applescript formatted as a single string
    # and return a list of arguments to pass to a subprocess
    # see https://gist.github.com/peter-jung/c1ba664e5306fe029cf02383b4145d0a
    return [item for x in [("-e",l.strip()) for l in script_string.split('\n') if l.strip() != ''] for item in x]

def applescript_run_script (script_args):
    # run applescript in a subprocess and return results
    proc = subprocess.Popen(["osascript"] + script_args, stdout = subprocess.PIPE)
    results = proc.stdout.read().strip()
    return results

def applescript_run (script_name, path="/my/default/path/"):
    # open an applescript, format as subprocess args, run & return results
    as_list = applescript_to_list (script_name, path)
    as_str  = applescript_list_to_string (as_list)
    as_args = applescript_string_to_args (as_str)
    return applescript_run_script (as_args)
 
print (applescript_run ("hello_world")) 

hello_world.applescript

use AppleScript version "2.4"
use scripting additions

do shell script "echo " & " Hello, World!"

this also works, lol:

!{'osascript ' + path + 'hello_world' + '.applescript'}
