<h1>Controlling other Applications from MacPython</h1>
<p>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:</p>
<blockquote><pre><tt>
import Finder
f = Finder.Finder()
print f.get(f.window(1).name)
</tt></pre></blockquote>
<p>is identical to the following piece of AppleScript:</p>
<blockquote><pre><tt>
tell application "Finder"
get name of window 1
end tell
</tt></pre></blockquote>
<p>To send AppleEvents to an application you must first create the Python
modules interfacing to the terminology of the application (what
<tt>Script Editor</tt> calls the "Dictionary"). Use the IDE menu command
<tt>File->Generate OSA Suite...</tt> for this. For more control run</p>
<blockquote><tt>
pythonw .../Lib/plat-mac/gensuitemodule.py --help
</tt></blockquote>
<p>from a terminal window.</p>
<h2>Creating a scriptable application in Python</h2>
You can also create a scriptable application in Python, but this is not
very well documented. For Carbon
applications you should look at the <tt>MiniAEFrame</tt> module.
