Что-то вы гоните насчет "привычного вида формата 755 и 644". Я вот вообще не понял что это!😳
Действительно, что означают цифры которые мы получили в прошлом посте?
Это кодировка, заключающая в себе режимы доступа к файлу.
Подробней можно почитать в статье про chmod.
Там можно увидеть альтернативное обозначение того же самого с помощью символов r w x, что значит чтение, запись, исполнение.
Чтобы преобразовать восьмеричное число в такое обозначение в Python есть готовая функция
>>> stat.filemode(0o755)
'?rwxr-xr-x'
Мы видим 3 группы по 3 символа, дающие 3 типа доступа для 3 типов юзеров.
А что за знак вопроса в начале?
Давайте передадим в эту функцию необрезанное значение от os.stat
>>> stat.filemode(os.stat(path).st_mode)
'drwxr-xr-x'
Это данные, которые мы безжалостно обрезали в прошлый раз😼
Первый символ обозначает тип объекта. Это может быть файл (-), директория (d) или симлинк (l).
Вот простая схема данной кодировки
[1][3][3][3]
│ │ │ │
│ │ │ └──> Others Permissions
│ │ └─────> Group Permissions
│ └────────> Owner Permissions
└───────────> File Type
(разверните экран если вы с телефона)
Если вы попробуете получить пермишены для симлинка то получите пермишены для файла
>>> path = '.venv/bin/python3'
>>> stat.filemode(os.stat(path).st_mode)
'-rwxr-xr-x'
Чтобы получить свойства именно симлинка, нужно это явно указать
>>> stat.filemode(os.stat(path, follow_symlinks=False).st_mode)
'lrwxrwxrwx'

More thoughts on spinning.
I hope you'll indulge me with this detour/personal journey of mine.
Processing and spinning wool seems an unnecessary and tedious task when there is everything else to worry about. However, some animals, like sheep, can be dual purpose. Why not learn to utilize what else they have to offer?
For some of us, the fiber is so worthwhile that we'd keep animals just for that purpose alone! (Hence my alpaca obsession - plus they are cheap therapy!)
The reason why I'm starting to love spinning is because it is a mindful, yet mindless task that you can simply pick up and tend to without thought. Just feeling, stretching, twirling.
With knitting, you must actively think. Processing and spinning fiber is a perfect complement to the art, a duty to put thoughts to rest and focus only on how the fiber feels.
It's not about getting it done quickly, it's not about profit. It's about enjoying your time and feeling empowered in what you're able to create with your own hands.

And thoughts on your environment's impact on how dirty your fleece gets

How things are going.
This is a Golding top whorl drop spindle. They kindly sent me some kind of hideous fiber to experiment with, which I gladly did, although I found it awful to work with. Probably not the best intro to spinning.
I skirted and clouded a small portion of Obsidian's fleece to see how it does in comparison. My hand carders are still sitting in my PO box, so I still have to wait for that - it makes the fluffing easier. No wash, just taking bits of vegetable matter out, and I gotta tell ya, it is really messy. Fluffing and picking seemed to get a lot of dust out, so spinning isn't that dirty, actually. It may even be giving it more grip.
It is far easier to spin that I expected. People say alpaca is not a good wool to start with because it's too slippery, but I found it extremely easy to draft and spin evenly. It may have something to do with the generous 3" of staple length.
I will try to record a short video of the skirting process tomorrow.
Still new, but learning.
