Thats because IDLE is an IDE so it interceprts the exit
(actually it intercepts the esception that exit() generates)
Thats what you want otherwise you'd constantly have to
restart IDLE. But when you run your program for
real - from Windows explorer for example it will just exit.

sys.exit() will do that when you run the program standalone.

If its a GUI program in Tkinter you can also use the root
quit command to quit the GUI mainloop which usually exits
the program too. But testing Tkinter programs from within
IDLE(which is itself a Tkinter program) has always been
a wee bit tricky, its better to always do your final test run
outside of IDLE IMHO. After all thats how the program
will eventually be used!
