Accessing the files by last modified time

Hi

I am new to the python programming language.

I've been trying to write a script that would access the last modified file in one of my directories. I'm using Win XP.

I saw a similar topic, on the forum before, however the reply using (os.popen) didn't work out for me. I'm not sure whether it was due to syntax errors either.

Thanks,
Sangeet

Recursively or non-recursively?
Live monitoring or just one-time?
What was the forum post in question?

In the simple case, you just need to stitch together these functions:
http://docs.python.org/library/os.html#os.stat
(note the .st_mtime attribute of the result)
http://docs.python.org/library/os.path.html#os.path.join
with one of these functions:
http://docs.python.org/library/os.html#os.listdir
http://docs.python.org/library/os.html#os.walk

Cheers,
Chris

import os
import glob

path = r"c:\one\of\my directories\*"

youngest_file = max(glob.glob(path), key=os.path.getmtime)

Modifying a time.struct_time
Hi!

I'm trying to create a struct_time that is e.g. one year ahead or a
month back in order to test some parsing/formatting code with different
dates.

Now, the straightforward approach is

t = time.localtime()
t.tm_year += 1

This fails with "TypeError: readonly attribute"....

An object is and isn't an instance of a class at the same time
I was debugging some code using isinstance() to make sure the correct object was been passed to the method and came across something that is really ticking me off.

I have a class called 'Jitem' in its own file called 'jitem.py'. It's part of a package called 'jukebox'. I also have '__all__'...

PyWarts: time, datetime, and calendar modules
The interface for these modules is not intuitive. Instead of creating
true OOP objects we have lists and strings. Any calendar object should
expose string names of both: days of the week and months of the year.
It seems one (or possibly more) of the three expose this important
info however i...
