Теперь запакуем строку.
В этом случае следует передавать тип данных bytes.
>>> struct.pack('=s', b'a')
b'a'
Для записи слова следует указывать количество символов.
>>> struct.pack('=5s', b'hello')
b'hello'
Кстати, запакованный вид соответствует исходному тексту. Всё верно, символ есть в таблице ASCII, то есть его код попадает в диапазон 0-127, он может быть записан одним байтом и имеет визуальное представление. А вот что будет если добавить символ вне ASCII
>>> struct.pack(f'=s', b'ё')
SyntaxError: bytes can only contain ASCII literal characters.
Ошибка возникла еще на этапе создания объекта bytes, который не может содержать такой символ. Поэтому надо кодировать эти байты из строки.
>>> enc = 'ёжик'.encode('utf-8')
>>> struct.pack(f'={len(enc)}s', enc)
b'\xd1\x91\xd0\xb6\xd0\xb8\xd0\xba'
Заметьте, длина такой строки в байтах отличается от исходной длины, так как символы вне ASCII записываются двумя байтами и более. Поэтому здесь формат создаём на лету, используя получившуюся длину как каунтер токена.

🗣#Farcaster: Project Acquired by Neynar — What’s Next
Recently, the Farcaster founder announced
a shift from a social platform toward a crypto-wallet–first model.
Yesterday, another major update followed — Farcaster has been acquired by Neynar
Neynar
is the core infrastructure and API provider for Farcaster (similar to Alchemy or Infura), powering most applications, bots, and tools across the ecosystem.
What changes after the acquisition:
🟢 Farcaster founders step away from day-to-day operations to focus on new projects.
🟢 Part of the team joins Neynar, while others exit.
🟢 The protocol will continue operating and is not being shut down.
🟢 The $180 million in raised funding will be returned to investors
🟢 According to the founders,
Neynar is the best-positioned team to scale Farcaster further, with a strong focus on developers and infrastructure.
What to do now:
✔ Check your Neynar points here
Neynar is expected to publish a detailed roadmap soon, outlining their vision for the future of the Farcaster protocol.
