there is no exitfunc in sys module

[Hameed Khan]

hi,
i was reading the manual for sys module. i found a
description for a function known as exitfunc. and it
says the function installed by
sys.exitfunc(cleanUpFunc) call will be called when the
interpreter exits. but when i try to call this
function on Python interactive prompt it says there is
no attribute named exitfunc in sys module.

###Traceback (most recent call last):
File "<stdin>", line 1, in ?

i am wondering that only i dont have this in my sys
module or it is being deleted from sys module. and if
only i dont have this function what reason it could be
that i dont have this function.

Thanks,

It doesn't exist by default. It's a function that you set up to be
called at termination. Try this::

import sys

def outtahere():
print "Okay, I quit"

sys.exitfunc=outtahere

print "program starting"
# do something
print "program done, now exiting"
