Launch AppleScript from Python

I have a working Applescript that automates some tasks in photoshop. I am trying to wrap a Python script around it for batch processing of files.

What I want is this

<psudocode>
for each file in dir
     applescript.scpt filename
     (wait until applescript finishes)
     Process result files

Do some other things
Done.
</pseudocode>

How do I launch Applescript from within Python (without HEREDOC or other similar things where I define the whole script in Python) so I can pass it a variable and have it work with a given folder?

PS: This post and similar like it are NOT the answer to my question. They are using heredocs and concatenated strings. That's not what I want. I have a VERY long script that I just want to pass a variable to so I can process files in a batch.

I like to use subprocess.

from subprocess import check_output

def get_result(cmd, args):
  out_put = check_output("%s %s" % (cmd, args), shell=True)
  return out_put

dir = raw_input("Directory: ")
files = get_result("ls", dir)
for file in files.split(' '):
  for f in file.split('\n'):
    results = get_result("applescript.scpt", f)
    print results

Open in new window

hope this helps. This is for windows so I'm not sure if this exactly would work for OS X as I don't have a machine to code this on... tell me if anything doesn't work etc. Hopefully you get the idea :)

I ultimately used:
on run {somevar}
    tell application "app"
    --Do things---
   end tell
end run

This mean that I could use subprocess.Popen to pass a variable the script and it will work.
