Filer and sort files by modification time in a directory - tester_V - May-02-2024
Greetings!
I need to filter files by file names, sort by the last modification time and process them.
I got this code but it does not work.
import glob, os
pt = "C:/PS_Power-Shell_scripts/Files/File.*"
all_files = glob.glob(pt)
all_files.sort(key=lambda x: x[1], reverse=True)
for file in all_files :
print(f" -- {file}") Could you help me with this?
Thank you.

Try
all_files.sort(key=lambda x: os.path.getmtime(x), reverse=True)

I would not lie, I Googled it and I do not understand it. I actually come up with a "readable' one and it works.
I'm not sure if it is a good code or not. Sorry about that!
lst_ogs = []
for item in Path(host_path).iterdir() :
if item.is_file() :
fname = Path(item).name
#print(f" .. {fname}")
if fname.startswith("some_log") :
lst_ogs.append(item)
lst_ogs.sort(key=os.path.getmtime,reverse=True) Thank you!

Maybe this will help with the understanding part?
from pathlib import Path
import os
mydir = Path('/home/pedro/tmp/')
# get all files
filelist = [filename for filename in mydir.iterdir() if filename.is_file()]
# copy filelist
old_list = filelist.copy()
# sort filelist according to os.path.getmtime
filelist.sort(key=os.path.getmtime, reverse=True)
# compare the 2 lists
for f in range(len(filelist)):
print(filelist[f])
print(old_list[f])To get the actual date of modification:from datetime import datetime
def modification_date(filename):
secs = os.path.getmtime(filename) # like: 1634870901.972196
dt = datetime.fromtimestamp(secs)
date = dt.strftime("%A %B %Y %H:%M:%S.%f")
print(f'file is: {f}')
print(f'last modified time in epoch seconds: {secs}')
print(f'date of last modification was: {date}\n')
mydir = Path('/home/pedro/tmp/')
file_gen = (filename for filename in mydir.iterdir() if filename.is_file())
for f in file_gen:
modification_date(f)
