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'

Operation Paperclip was a secret U.S. program after World War II. It brought over 1,500 German and Austrian scientists to the United States. Many had been members of the Nazi Party. They worked on military, aeronautics, and space research. Their Nazi pasts were ignored so the U.S. could use their expertise and keep it from the Soviet Union.

GERMANY IS A NAIVE PAWN OF THE USA WITH SEEMINGLY NO POWER TO SAVE ITSELF.
The #USA has failed against #Russia:
• It has missed its military target and this failure is damaging America’s prestige as the greatest military power.
• The #sanctions war against Russia are a complete failure. The West is weakened while Russia strengthens. The #IMF figures speak volumes: Germany doesn’t even make the list.
“The primary interest of the United States through the last century-that is, #WW1, #WW2, and the #ColdWar, has been the relationship between Germany and Russia.
If united, those two would be the only power that could threaten us-and so we have to make sure that doesn’t happen.”
George Friedman
The aim is therefore to prevent Germany from teaming up with Russia.
If it is not possible to weaken Russia as a major opponent, there is the option of preventing the alliance by turning #Germany and Russia into enemies and/or destroying Germany (for the third time after 1918 and 1945)
Operation Osoaviakhim was a secret Soviet program after World War II. Over 2,500 German scientists, engineers, and technicians and their families were taken from the Soviet zone of Germany to the USSR.
They worked on Soviet military, weapons, and rocket technology. The goal was to use German expertise to strengthen the USSR and keep it from falling into Western hands.
Basically the Soviet version of operation Paperclip📎

Project MK‑ULTRA was a secret CIA program during the Cold War. It ran from 1953 to 1964. The CIA tested mind control using LSD, hypnosis, electroshock, and sensory deprivation. Some experiments gave drugs to people without their knowledge, isolated subjects for long periods, or exposed them to extreme stress. Under Dulles, the CIA opened secret prisons in West Germany and Japan, advised by Walter Schreiber, former Surgeon General of the Nazi army. Schreiber had avoided imprisonment after World War II and was brought to the West by U.S. intelligence, likely as part of programs like Operation Paperclip. Most records of MK‑ULTRA were destroyed in 1973, but investigations later revealed the program.
