Hi Steve,
IDLE's subprocess never actually exits, so the atexit handler will not
be called. Forcing an exit with sys.exit() will be caught and the
subprocess will still not exit.
I suggest filing a bug at bugs.python.org.

Hello Idle-dev folks,
I tried this on the python list, with no luck. ;-(
I hate to bother you with a basic user question, but I'm not sure where else to
go. Is there a better list for this?
thanks,

Hello Pythonistas!
I'm trying to get this program, which works on the command line, to run
correctly in the IDLE environment:
import atexit
print "This is my program"
def exit_func():
print "OK.. that's all folks!"
atexit.register(exit_func)
print "Program is ending..."
When I run this on the command line I see:
This is my program
Program is ending...
OK.. that's all folks!
When I run this in IDLE I see:
This is my program
Program is ending...
But the atexit handler is never called. ;-(
I tried to fish through the IDLE source to see how the program is actually
called, and I decided it looked like it was being invoked with with os.spawnv,
but I'm not sure why this would defeat the atexit handler. Anybody know? I'd
like to register such a function in my module, but I need it to work in IDLE so
that students can easily use it.
thanks!
