Last Modified File in Python?

Question

So I'm trying to write a script that allows me import the most recently modified file from a directory. I've looked at the glob and os.listdir commands but they don't seem to do it (I get errors). Any thoughts?

import os
import glob
newest = max(glob.iglob('Directory Name'), key=os.path.getctime)
print newest
f = open(newest,'r')

I get an error:

max() arg is an empty sequence

Would something like os.stat work better?

As error says - glob.iglob returns an empty sequence. Maximal value from empty sequence is unknown. Therefore exception is raised. — Łukasz Rogalski, Jul 16 '15 at 14:31
At the end of the *glob*, not the end of the line of code. Put it right after `Directory Name`, before the closing quote. — Kevin, Jul 16 '15 at 14:34

Try:

newest = max(glob.iglob('Directory Name/*'), key=os.path.getctime)

@champ8686: Is the directory empty? Did you spell its name right? – Kevin Jul 16 '15 at 14:46
I got it. Thanks guys! The /* was needed. – yarz-tech Jul 16 '15 at 14:59
