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. #libs#basic

🌎 The coldest known place in the universe is the Boomerang Nebula, located about 5,000 light-years from Earth. Its temperature is just 1 kelvin, or –272°C, which is even colder than the background temperature of space. This nebula formed from rapidly expanding gas blown out by a dying star. ✨ #space⚡#universe⚡#astronomy 👉subscribe Interesting Planet 👉more Channels ​

🌎 The Boötes Void is an enormous empty region of space, spanning about 330 million light-years across. This cosmic void contains far fewer galaxies than expected, making it one of the largest known gaps in the observable universe. ✨ #space⚡#astronomy⚡#universe 👉subscribe Interesting Planet ​

🌎 At the edge of the observable universe, mysterious “dark flow” tugs galaxy clusters in the same direction, hinting at unseen forces or realms beyond our cosmic horizon. This puzzling movement can’t be explained by known gravity alone, sparking debate about what lies outside the visible universe. ✨ #space⚡#universe⚡#cosmology 👉subscribe Interesting Planet ​

🌎 Scientists researching the mysteries of parallel worlds often reference "brane theory," which suggests our universe could be a 3D surface, or 'brane,' floating in higher-dimensional space. In this model, multiple branes—each a universe with its own laws—could exist, and gravity may leak between them, which physicists are testing with experiments at facilities like CERN. ✨ #physics⚡#universe⚡#dimensions 👉subscribe Interesting Planet 👉more Channels ​

🌎 Hidden in the vast cosmic darkness, rogue planets drift alone through space without orbiting any star. These “orphan worlds” form when gravitational forces eject young planets from their home systems. Some estimates suggest our galaxy may contain more rogue planets than stars. ✨ #universe⚡#astronomy⚡#exoplanets 👉subscribe Interesting Planet ​

🌎 Mysterious dark matter makes up about 27% of the universe, but it does not emit or absorb light, making it invisible. Scientists detect dark matter only through its gravitational effects on galaxies and galaxy clusters. The leading candidates for dark matter particles are called WIMPs—Weakly Interacting Massive Particles. ✨ #space⚡#universe⚡#astrophysics 👉subscribe Interesting Planet 👉more Channels ​

🌎 An ancient mystery lingers at the center of our galaxy—a supermassive black hole called Sagittarius A*. Its powerful gravity bends space and time, hiding beyond a swirling cloud of stars and gas. This invisible giant shapes the Milky Way, anchoring everything around it with immense, unseen force. ✨ #space⚡#blackhole⚡#universe 👉subscribe Interesting Planet ​
