# Controlling other Applications from MacPython

Python has a fairly complete implementation of the Open Scripting Architecure (OSA, also commonly referred to as AppleScript), allowing you to control scriptable applications from your Python program, and with a fairly pythonic interface. This piece of Python:

> `

>     import Finder

>     f = Finder.Finder()
>     print f.get(Finder.window(1).name)

> `

is identical to the following piece of AppleScript:

> `

>     tell application "Finder"
>     	get name of window 1
>     end tell

> `

To send AppleEvents to an application you must first create the Python modules interfacing to the terminology of the application (what `Script Editor` calls the "Dictionary"). Use the IDE menu command `File->Generate OSA Suite...` for this. For more control run

> `pythonw .../Lib/plat-mac/gensuitemodule.py --help`

from a terminal window.

## Creating a scriptable application in Python

You can also create a scriptable application in Python, but this is not very well documented. For Carbon applications you should look at the `MiniAEFrame` module.
