except: block running even though try: ran successfully

January 17, 2022

This code is to print the most-recently-modified directory. A directory with no sub-dirs will throw and exception, so I put it in a try-except block. The code in both sections is running!?

  try:
  newest = max( [x for x in os.listdir('.') if os.path.isdir(x)], key = os.path.getmtime)
  print(newest)
  exit()
except:
  print("No directories found!")
  exit()

I see this output (‘bin’ is the correct newest sub-directory). The print from try: and except: has executed.

bin
No directories found!

What’d I miss? Thanks for your consideration.

>Solution :

exit() is raising an exception. Try:

try:
    newest = max( [x for x in os.listdir('.') if os.path.isdir(x)], key = os.path.getmtime)
    print(newest)
except Exception:
    print("No directories found!")
finally:
    exit()
