Один из самых удобных способов записать данные это использование готовых форматов, такие как JSON или YAML.
Из плюсов такого подхода стоит отметить вот что:
🔸 готовый, повсеместно используемый и поддерживаемый формат
🔸 простой и понятный файл, удобочитаемый для человека
🔸 можно легко редактировать в любом текстовом редакторе без специальных программ и библиотек
Но есть и минусы
🔹 затраты времени при записи файла (кодирование данных в нужный формат строки)
🔹 затраты времени при чтении файла (декодирование данных в Python объекты)
🔹 размер файла увеличивается из-за разметки данных (скобки, запятые, переносы, отступы...)
🔹 перед записью все данные должны быть помещены в память в полном объёме (не всегда)
🔹 при чтении необходимо считать весь файл в память и только потом декодировать данные
Если нужно писать немного данных в несколько файлов, то затраты по времени не ощутимы. Обычно это файлы конфига или какие-либо метаданные. Это отличный вариант под такие задачи.
Есть и другой поход к записи файлов - это бинарные файлы. Используется, когда данных достаточно много и никто их не собирается читать глазками😳.
🔸 очень быстрая запись
🔸 чтение значительно быстрей чем JSON, YAML итд
🔸 размер файла значительно меньше, так как нет разметки
🔸 можно записывать данные по мере поступления не загружая всё в память
🔸 можно извлечь любую часть данных независимо
Из минусов
🔹 нужно определить свой формат записи данных (если не используете готовую спецификацию определённого формата)
🔹 не получится открыть файл и визуально понять что там записано, а для чтения файла потребуется знать его спецификацию.
🔹 не так-то просто создать такой файл без специальной библиотеки
В таком виде удобно записывать большой массив любых однородных данных. Например, мониторинг валютной биржи или кэшированная анимация 3D геометрии.
(Это не означает что нельзя записать данные разного типа, просто это будет не так удобно)
Представьте себе JPG-картинку. По сути это немного мета-информации и большой массив пикселей. Тоже самое со звуком или видео файлом. Поэтому, если вы попробуете открыть картинку в текстовом редакторе вы увидите что-то вроде такого
f15d cd29 a564 4578 ...
09e2 9bc4 a696 1253 ...
84e9 4de1 3b23 c24a ...
2534 5161 28e0 709d ...
...
Это и есть записанные байтики. И для их чтения требуется определённый софт который знает что с ними делать. Под каждый тип файла.

Unraveling the Scam NFT Epidemic Dominating the Past Week
The last week has been filled with cases of spam mailings of pseudo-NFT projects that supposedly entitle you to tokens or promise something else. But this is not true, if you received such an NFT, they are trying to deceive you.
✔️Do's: Nothing. Ignore them. If they clog your wallet, burn them.
🚫Don'ts: Follow the links in the description of these NFTs and connect your wallet. There is a risk of the balance being written off.
☝️ NFTs of good projects are valuable, they don’t just send them. If you did not pay for them or did not participate in the activities of this project, you will not be sent NFTs. So remember to be sane and safe.
All NFTs shown in the photo are ⚠️
