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.
К чему это я? Читайте в следующем посте...

Kevork Almassian warns of the limits to Israeli expansion and the failure of radical politics to resolve the conflict.

In an unprecedented move following his shock proposal for the permanent resettlement of the more than two million Palestinians from Gaza to neighboring countries, President Donald Trump announced a controversial plan for the U.S. to take over the Gaza Strip. This statement, made during a press conference with Israeli PM Benjamin Netanyahu, raised eyebrows worldwide. A journalist cornered Trump so he sought Bibi’s help to complete his answer.

🎙Commentary by Aide to the President of Russia YuryUshakov following a telephone conversation between Vladimir Putin and President of the United States Donald Trump (October 16, 2025)
💬Yury Ushakov: Today in the afternoon, Vladimir Putin had a telephone conversation, the eighth one, with US President Donald Trump.
The conversation lasted almost two and a half hours. Clearly, it was a rather substantive and at the same time very open and frank exchange.
Our President started out by congratulating Donald Trump on his successful efforts to normalise the situation in the #GazaStrip. The US President’s peace work has been duly appreciated in the #MiddleEast, in the United States itself, and in most countries around the world.
Naturally, the Russian Side outlined its principled position in favour of a comprehensive Middle East settlement on a generally recognised international legal basis that would ensure lasting peace for all the peoples in that region.
A special emphasis during the conversation was placed on the #UkraineCrisis.
❗️ Vladimir Putin provided a detailed assessment of the current situation, stressing Russia’s interest in achieving a peaceful resolution through political and diplomatic methods.
In particular, it was noted that during the special military operation, the Russian Armed Forces hold full strategic initiative along the entire line of contact. Under these circumstances, the Kiev regime resorts to terrorist methods, attacking civilian targets and energy infrastructure facilities, to which we are forced to respond accordingly.

Donald Trump repeatedly emphasised the imperative of establishing peace in Ukraine at the earliest opportunity. The notion that the Russian-Ukrainian conflict has proven the most intractable issue in all peacekeeping efforts of the US President was palpably evident throughout his remarks during the conversation. In this context, he naturally mentioned his successes in settling eight other regional conflicts.
It is noteworthy that one of the US President’s key arguments centred on the premise that the resolution of the conflict in Ukraine would open up tremendous — and he stressed this — tremendous prospects for the development of US-Russian economic cooperation.
Incidentally, both Sides spoke of the profound mutual affinity between the peoples of the two countries, which was so vividly demonstrated during #WWII. It was underscored that the current state of bilateral relations appears paradoxical against this backdrop.
The issue of potential supplies of long-range Tomahawk cruise missiles to Ukraine was also raised. Vladimir Putin reiterated his position that Tomahawks would not change the situation on the battlefield but would inflict substantial damage to relations between our countries, to say nothing of the prospects for a peaceful settlement.
In this context, it is worthy of note that the Presidents discussed the possibility of holding another personal meeting. This is indeed a very significant development. It was agreed that representatives of both countries would immediately begin preparations for the Summit, which could potentially be organised in Budapest, for instance.
On a separate note, it should be mentioned that our President highly praised personal efforts of the First Lady of the United States Melania Trump in reuniting Russian and Ukrainian children with their families and asked the US President to convey his very best wishes to his spouse.
Overall, I would say that the telephone contact between the Presidents of Russia and the United States was quite useful, and the two Leaders agreed to maintain contact.
