System wird ausnahmsweise nicht beendet

Ich rufe die Funktion auf, um eine Textdatei zu öffnen. Bei Ausnahmen möchte ich das ganze Programm beenden. Der Code lautet wie folgt:

def get_words():
 print("File:",FILENAME)
 try:
 words = open(FILENAME, 'r')
 except FileNotFoundError:
 print("File {} not found.".format(FILENAME))
 sys.exit(1)
 except Exception as err:
 print("Unexpected Error opening {}".format(FILENAME))
 sys.exit(1)
 else:
 with words:
 words2 = words.read()
 wordlist = words2.split(" ")
 words.close()
 return wordlist
 pass

Ich rufe diese Funktion im folgenden Code auf:

words = get_words()

Wenn ich dies ausführe, erhalte ich den Fehler, dass During Handling of the above exception, another Exception occured. Bitte teilen Sie uns mit, warum so eine einfache Sache Fehler verursacht. Vollständige Rückverfolgung:

Lösung des Problems

Dies sollte das Problem beheben.

import sys
import os
def get_words():
 print("File:",FILENAME)
 
 if os.path.exists(FILENAME):
 with open(FILENAME, 'r') as f:
 words2 = f.read()
 return words2.split(" ")
 else:
 print("File {} not found.".format(FILENAME))
 sys.exit()
words = get_words()
