4 measurements spanning 6 days, net -4. Dots are measurements; the straight line between them is drawn to join them, not to claim we know the path taken in between — snapshots are recorded only when a count changes, so gaps mean “no change observed”, never “interpolated”. The vertical axis spans 4,276–4,282 and does not start at zero.

Engagement

13 posts held, back to 19 April 2023the reader has not yet reached the start of this channel’s public history, so older posts may sit further back, unread. Read across 5 pagesof Telegram’s post history, 20 posts per page.

Nothing published in the last 30 days. ERR and ER are rolling 30-day measures, so there is nothing to compute — we hold 13 posts for this entry, the most recent from 7 October 2025. An engagement rate over an empty window would be a number about nothing.

Reaction mix

634 reactions across 13 posts, in 13 distinct kinds. The most used accounts for 35.0% of them.

No sentiment is inferred, and none should be read in. This table is ordered by count and by nothing else. Emoji do not carry stable meaning across languages or communities — 🙏 is thanks in one channel and mourning in another — so we publish which ones were pressed and how often, and pass no judgement on what an audience meant by them.

Precision. Telegram publishes reaction counts per emoji and short-forms each one — 4.34K, 1.2M — so any single kind at or above 1,000 reaches us at three significant figures, and only counts below 1,000 are exact. The shares above are ratios of those figures and carry the same error. This is also why the total here can differ slightly from a reaction total printed elsewhere on the page: both are sums of the same rounded parts, taken over samples with different edges.

Coverage. Reactions were read on 13 of the 13 sampled posts in this sample. Summed by Telegram’s own count on each post — not by adding up the per-emoji breakdown above — those same posts carry 634reactions in total: the kind of figure the paragraph above means by “a reaction total printed elsewhere on the page”.

Measured over the 13 most recent posts we hold, published 19 April 2023 to 7 October 2025, using the newest reading held for each. Telegram Stars are excluded: they are a payment, not a reaction, and they have their own section.

Исторический момент: выходит Python 3.14 и они там отменяют GIL. Дожили, поздравляю нас!🎉 Всем, кто хоть раз в жизни писал код в несколько тредов на питоне и ломал голову, почему не ускоряется😁 Это ваш день! Глобальная блокировка десятилетиями неявно ограничивала интерпретатор, а мы пользовались multiprocessing-ом, расширениями на плюсах и всякими костылями, чтобы задействовать все ядра процессора. Это первый стаб

Вы, наверное, знаете, что из-за того, что числа в памяти представлены в двоичной форме, в Python есть ошибка вида print(0.1 + 0.2) # 0.30000000000000004 В Python модуль decimal поддерживает точную арифметику десятичных чисел. Она важна в областях, требующих высокой точности, например, в финансах или научных расчетах. А вот кто скажет, почему возникает разница в примерах ниже? 1️⃣ from decimal import Decimal a =

Вау, в Python будет можно по желанию отключить GIL. В мейн буквально пару часов назад вмержили эту настройку https://github.com/python/cpython/pull/116338 GIL (Global Interpreter Lock) — это механизм в CPython, который предотвращает одновременное выполнение нескольких потоков. Это всю дорогу означало, что даже если мы пишем программу на Python как многопоточную, то в любой момент времени может выполняться только о

Генератор кортежей Генераторы списков — это конструкции вида [x for x in range(5)] # [0, 1, 2, 3, 4] Чаще всего их используют для создания списков на лету. Но можно создавать и словари, если использовать фигурные скобки и пары значений, разделенных двоеточием: {n: n**2 for n in range(5)} # {0: 0, 1: 1, 2: 4, 3: 9, 4: 16} Кортеж так создать не получится, потому что круглые скобки зарезервированы под генераторные

Вопрос от студента: как использовать в map функцию с параметром? Все, кто сталкивался с map(), знают, как использовать её, если параметры не нужны. Например, с map() можно привести числа в списке к абсолютным значениям numbers = [-1, 2, -3, 4, -5] absolute_values = list(map(abs, numbers)) print(absolute_values) # [1, 2, 3, 4, 5] Или преобразовать все строки в верхнему регистру names = ["alice", "bob", "charlie",

try, except, finally и оператор return в Python: как работает finally при наличии return Python предоставляет механизм обработки исключений с помощью операторов try, except и finally. Когда внутри блока try возникает исключение, оно может быть перехвачено и обработано в блоке except. Кроме того, блок finally позволяет выполнять нужные вам действия независимо от того, произошло исключение или нет. Но если внутри бло

Стек и очередь Идеи стека и очереди часто встречаются в различных языках программирования. Давайте разберемся, в каких ситуациях их применение уместно и удобно программисту. С очередями мы сталкиваемся практически везде. В магазине очередь – это группа людей, которые стоят друг за другом, например, на кассу с продуктами. Тот, кто стоит ближе к кассе, оплатит свои продукты первым. В программировании очередь работае

Showing the 12 most recent of 13 posts we hold for @coolpython. View and reaction counts are the latest single reading for each post, not a live figure, and a recent post is still accumulating both. A view count marked was rounded by Telegram before we ever saw it — t.me prints views in full below 1,000 and to three significant figures above, so ≈1,200,000 means somewhere between 1,150,000 and 1,249,999. Unmarked counts are exact. Text is reproduced from the public post preview and truncated for length.

Shares as published, totalling 99%. No per-option vote count is published by Telegram, so none is shown.

Percentages only — there are no per-option vote counts here, because Telegram publishes none.The public post preview gives each option’s share and a single voter total, and nothing else. Multiplying one by the other would produce a per-option tally that looks measured and is not: the shares are rounded to whole numbers before we ever see them. We print what was published and leave the column that does not exist empty.

The shares need not add up to 100.Rounding alone puts many polls at 99 or 101. A poll that allows more than one answer per voter runs well past 100 by design, and several here do. The bars are drawn against a fixed 100% track at each option’s own percentage rather than normalised to the total, so a poll that exceeds it shows that it does instead of being quietly rescaled.

Read from the 13 most recent posts we hold, published 19 April 2023 to 7 October 2025. Telegram labels each poll by kind — an anonymous poll, a quiz, a closed set of final results — and that label is reproduced rather than paraphrased.

Mentions

Names

Channels on the register whose handles appear in this channel's posts.

A mention is a weaker signal than a forward and is counted separately for that reason — naming a channel is not republishing it, and a handle in a post body is easy to place deliberately. The post counts beside each row below are distinct posts in which the handle appeared, from posts we have read on both sides — the “Named by N registered channels” figure above is a different count, of distinct NAMING CHANNELS rather than posts, and is not the sum of the rows under it.
