This code snippet allows you to list the files in a folder sorted by "last modified date". The tuple returned by the os.stat() function contains amongst other things the last modified date, which is then converted by the time.localtime() function to a tuple that is ideal for sorting. You can select the folder and the type of file you want to display.

Looks like someone ate it! I reloaded the submission.
Good thing I checked the comments! Thanks ...

hi I am doing something very similar what i want is to be able to pull the 6 latest modified / original file like so ...
ex1.txt = 28/06/10
ex2.txt = 27/06/10
ex3.txt = 24/06/10
ex4.txt = 19/06/10

I am using the same code as above with a few tweaks for other operations i need to do in this program

at the moment i get the 6 latest files but some of them have the same date i need to get the latest files but only 1 per date
this is what i get atm
ex1.txt = 28/06/10
ex2.txt = 28/06/10
ex3.txt = 28/06/10
ex4.txt = 17/06/10
ex5.txt = 17/06/10
ex6.txt = 16/06/10

This code ROCKS, it's exactly what I was looking for.

By any chance, is there a way to add a count of files by file date? That is, if I have 10 files created Dec 1, and 25 files created Dec 3, how could I add that?

Either way, glad you put this out there. Thanks again!

You can add this code to the end of the snippet code ...

print('-'*60)

# optional, count files with matching dates
date_name_list = []
for file in date_file_list:
    # extract just the filename
    folder, file_name = os.path.split(file[1])
    # convert date tuple to MM/DD/YYYY date format
    file_date = time.strftime("%m/%d/%y", file[0])
    date_name_list.append((file_date, file_name))

# contains date:count pairs
date_count_dict = {}
# contains date:[files] pairs
date_name_dict = {}
for date, name in date_name_list:
    # word_freq[word] = word_freq.get(word, 0) + 1
    date_count_dict[date] = date_count_dict.get(date, 0) +1
    date_name_dict.setdefault(date, []).append(name)

import pprint
print("Files with the same date:")
pprint.pprint(date_name_dict)
print('-'*60)
print("Same dates count:")
pprint.pprint(date_count_dict)

New to coding and python, I came across your script and wanted to use a slightly modified form ofit. I need to get only partial filenames. I have a set delimiter that I am able to use as a "drop from here" point and want to modifiy the output to use the shortened string. I assume I can use something along the lines of,

line.split(".") [0]

But I am not sure how to use it in this case. I am guessint that it would need to be somewhere in the for loop starting at line 37. Any help would be appreciated

if you want to drop everything after the last "." you would add this after line 39

file_name = ".".join(file_name.split(".")[:-1])

Here is a breakdown of that code

file_name = "test.file.txt"

file_name.split(".")
<<< ["test", "file", "txt"]

take a slice of that minus the last item in the list

["test", "file", "txt"][:-1]
<<< ["test", "file"]

then reinsert the remaining periods that were 'split' in step 1 with 'join'

".".join(["test", "file"])
<<<"test.file"

if you are wanting only the first part file_name then the code would be

file_name = file_name.split(".")[0]
like you posted above

Edited 4 Years Ago by ihatehippies: cuz

Sweet, file_name = file_name.split(".")[0] did exactly what I needed. Now that I have the formatI need it is on th the next step. Thanks ihatehippies for that clarification and thanks to vegaseat for throwing this up.
Hopefully I will have the full modified version to add (with notes) by the end of the day today.

anyone know how to mod this code to something like:
after the list has sorted, it can call the oldest file and try excute something like send this file to an email.
and also after which del the file.
Would be appreciated if any expertise will help. Thanks
