Python + bash
Если вам часто требуется запускать shell команды из Python-кода, какой способ вы используете?
Самый низкоуровневый это функция os.system(), либо os.popen(). Рекомендованный способ это subprocess.call(). Но это всё еще достаточно неудобно.
Советую обратить своё внимание на очень крутую библиотеку sh.
Что она умеет?
🔸 удобный синтаксис вызова команд как функций
# os
import os
os.system("tar cvf demo.tar ~/")
# subprocess
import subprocess
subprocess.call(['tar', 'cvf', 'demo.tar', '~/'])
# sh
import sh
sh.tar('cvf', 'demo.tar', "~/")
🔸 простое создание функции-алиаса для длинной команды
fn = sh.lsof.bake('-i', '-P', '-n')
output = sh.grep(fn(), 'LISTEN')
в этом примере также задействован пайпинг
🔸 удобный вызов команд от sudo
with sh.contrib.sudo:
print(ls("/root"))
Такой запрос спросит пароль. Чтобы это работало нужно соответствующим способом настроить юзера.
А вот вариант с вводом пароля через код.
password = "secret"
sudo = sh.sudo.bake("-S", _in=password+"\n")
print(sudo.ls("/root"))
Это не все фишки. Больше интересных примеров смотрите в документации.

How to use Fear & Greed and Altcoin Season indicators to make decisions?
If you trade or invest in crypto, these two indicators will help you understand the overall market sentiment and choose a more intelligent strategy. Let's look at what they show:
😨Fear & Greed Index. Current: 52 — Neutral
This index reflects the emotions of traders:
0–24 — Strong fear. Market is oversold, entry points are possible.
25–49 — Fear. Cautious mood, consolidation possible.
50–74 — Greed. Investors are confident, but they should be more careful.
75-100 — Strong greed. Overheating and rollback may occur.
🤔What to do:
If fear is high (especially <25) — consider purchases.
If you are very greedy (>75) — take profit, do not enter at highs.
💎Altcoin Season Index. Current: 17/100
This indicator shows who dominates the market — Bitcoin or altcoins:
<25 — Bitcoin Season: Capital Flows into Bitcoin, Alts Weaken.
25–75 — Mixed phase.
>75 — Altcoin Season: altcoins are actively growing.
🤔What to do:
Now (17/100) — Bitcoin dominates. Risks for altcoins are higher. Better to focus on BTC and wait for a trend change.
When >75 - you can look for alts with strong dynamics and enter them on growing interest.
