[Idle-dev] Fwd: atexit handler in IDLE?

[Steve Spicklemire]

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,
-steve

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.
