It is rarely a question of impossibility. It often enough is a sense that the person asking the question is approaching the problem from the wrong side. Often enough that sense is correct, often enough that sense is wrong. All the participants can do is take a clue from the question and then guess what respons would help this person best.

It's true, I've only been on this list a few weeks, although I've seen and been on the receiving end of the kind of "help" that feels more like being sneered at than help. Not on this list, but on Linux and similar lists. There does seem to be a "tough love" approach to "helping" people, and I haven't seen that it really helped that much, in other places that I've seen it in action over a period of time. I'm willing though to just see how it works on this list. Since I've been here, I haven't seen people come back who get that kind of approach, but a few weeks is too short a time to draw conclusions. Still, when people who need help don't come right back, that should be a first clue that they didn't get it. > > If that's > > impossible because they have something so wrong that you don't know > > what they're asking, that would be a good time to point it out and > > give them a chance to correct it. > > It is rarely a question of impossibility.

Communication in lists and forums is somewhat in the dark, because there's so little context in many of the conversations.

timers in threaded application
I know signals and threads are a bad mix, but I only discovered I was playing with fire a few minutes ago. I've been using the websocket-client library (https://pypi.python.org/pypi/websocket-client/) to interact with another system at work. It implements its own event loop, but doesn't seem to play nice with others. I used gtk/gobject for years. It implemented timeouts for you, you could integrate it with other event loops, etc. As far as I could tell, websocket-client implements none of that. I needed some timer functionality, so not thinking about it too carefully, I implemented it using signal.alarm. This worked pretty well, but I was experiencing mysterious hangs. This morning, looking through the websocket-client code to see if I'd missed something, I saw that it uses threads. So, that might be my problem. I still need timers, and for the moment I'm stuck with this package's event loop. What options do I have? I'm certainly willing to switch to another websocket client library if that will make all my problems go away. This is my first ws experience though, and I inherited some code which used websocket-client, so just went with what I had. Thx, Skip -- https://mail.python.org/mailman/listinfo/python-list

There's a reason for that. Inaccurate information is worse than none at all, because it's indistinguishable from accurate information without deep analysis. Also, often someone won't know the correct answer, but will recognize a wrong answer. In correcting the record, you come a bit closer to the truth. Sometimes all it takes is one wrong answer, and the discussion kicks off. ChrisA -- https://mail.python.org/mailman/listinfo/python-list

Which attribute you want depends on exactly what you mean by "the latest folder according to the latest date".

I've used something like the below to find the most recent file in a
directory tree (it also works for pulling other attributes like the
file-size from os.stat() results).
-tkc
import os
from operator import attrgetter
def dir_iter(root):
for fullpath in (
os.path.join(path, dir_)
for path, dirs, files in os.walk(root)
for dir_ in dirs
):
if os.path.isdir(fullpath):
yield fullpath
def find_latest(root,
which_time=attrgetter("st_mtime")
):
return max(dir_iter(root),
key=lambda fullpath: which_time(os.stat(fullpath))
)
if __name__ == "__main__":
from sys import argv
if len(argv) > 1:
root = argv[1]
else:
root = '.'
print(find_latest(root))
print(find_latest(root, which_time=attrgetter("st_ctime")))

Most certainly not. Try to use the normal way with just a name, e. g. for entry_a in a: ... Then use entry_a instead of a[i] for your comparison in the body of the for- loop. With that approach it's impossible to get an IndexError. If you still need the index to alter an entry in the list -- enumerate() is your friend: for index_a, entry_a in enumerate(a): ...

The code I had laying around that did something similar but processes both the dirs and the files, so when the OP asked for just dirs, I ended up with both belt-and-suspenders changes to it. So that isdir() check could readily be removed. -tkc -- https://mail.python.org/mailman/listinfo/python-list

If you go down a wrong path, people are going to try to warn you. For example, you were told several times, no that object really is a list, yet you argued with them on that point for several posts. Tough love or sneering? No, absolutely not. Communication difficulties? Yes! But not even close to wholly the fault of those who were trying to assist you. If you haven't been helped, it's not for lack of their trying. > I'm willing > though to just see how it works on this list.

And long-time posters have no problem telling other long-time posters when they do cross the line into bullying or trolling territory. Fortunately I've seen nothing but people wanting to help you with your ventures in Python programming responding to your queries, which I'm gratified to see. And many many newbies have been helped in their explorations of Python land. -- https://mail.python.org/mailman/listinfo/python-list
