subprocess с принудительным сбросом привилегий. Такой приём позволяет запускать команды даже в окружениях с потенциально небезопасным вводом, блокируя доступ к опасным системным вызовам и снижая риск эксплуатации.
import subprocess
import os
def safe_run(cmd):
# Запускаем процесс без наследования переменных окружения
env = {"PATH": "/usr/bin:/bin"}
# Сбрасываем привилегии, если процесс запущен от root
def drop_priv():
os.setgid(65534)
os.setuid(65534)
result = subprocess.run(
cmd,
env=env,

@pythonlreversed(), но работает она не со всеми структурами данных. Быстрый разбор:
✓ Список можно развернуть
reversed([1, 2, 3]) возвращает итератор.
list(reversed([1, 2, 3])) → [3, 2, 1]
✓ Кортежи тоже разворачиваются
Можно итерироваться по reversed((1, 2, 3))
✓ Множества не разворачиваются
reversed({1, 2, 3}) → TypeError: 'set' object is not reversible
Причина: множества *не имеют порядка*, а значит разворачивать нечего.
Если нужно развернуть множество — сначала сделай его списком:
list(reversed(list({1, 2, 3})))
