Taking the standard Python template Project as an example, you can
just add this method to your MyAppDelegate class:

     def applicationWillTerminate_(self, aNotification):
         NSLog( "Application will terminate." )

much like this (existing) one:

     def applicationDidFinishLaunching_(self, aNotification):
         NSLog( "Application did finish launching." )

The first method will be called when you type Cmd-Q or click on the
Quit menu entry. Instead of calling NSLog() you can do whatever you
need to. With aNotification.object() you should get the NSApp object,
I beliebe.

You can also register an object to observe equivalent "notifications"
posted by the NSApp object, in this case it is "NSApplicationWill\
TerminateNotification" using the class named NSNotificationCenter.
I tried that before and it works.
