Short code for EventGhost not working

[Patricia]

Hi Guys. I'm just starting to learn Python
I have a short script that is supposed to play a random wav file in a folder but only between 9 and 5
It returns an error and I'm not sure what I have done wrong

from os.path import isfile, join
from os import listdir
import random
import datetime

hr = datetime.datetime.now().hour

if hr < 9 or hr > 17: 
  exit()

#path you want to get wav files from
path = "C:\Sounds\Clock Sounds for EG\Doorbell"
onlyfiles = [ f for f in listdir(path) if isfile(join(path,f)) ]

onlywavfiles = []
for f in onlyfiles:
    if f[-3:] == "wav":
        onlywavfiles.append(f)

#generate random number based on number of available files
randomnum = random.randint(0,len(onlywavfiles)-1)

eg.plugins.System.PlaySound(path + "/" + onlywavfiles[randomnum], 1, False)

This is the error

Error:
    Traceback (most recent call last):
           Python script "9", line 9, in <module>
             exit()
         NameError: name 'exit' is not defined

Thanks Patricia
