Скорее всего уже слышали, что складывать строки через + это плохая практика. Падение производительности, и всё такое. Без лишних слов, давайте измерять: from timeit import timeit def t1(): # складываем 10 строк через + из переменной t = 'text' for _ in range(1000): s = t + t + t + t + t + t + t + t + t def t2(): # склеиваем список строк через метод join arr = ['text'] * 10 for _ in range(1000): s = ''.join(arr) def t3(): # складываем через + но не из переменной а непосредственно инлайн объекты for _ in range(1000): s = 'text' + 'text' + 'text' + ... # всего 10 раз Теперь каждую строку склейки запустим по 10М раз >>> timeit(t1, number=10000) 0.21951690399964718 >>> timeit(t2, number=10000) 1.4978306379998685 >>> timeit(t3, number=10000) 0.2213820789993406 Хм, а нам говорили что через "+" это плохо и медленно ))) 😁 Тут стоит учитывать, что речь идёт о склейке множества длинных строк. Давайте изменим условия: def t4(): t = 'text'*100 for _ in range(1000): s = t + t + t + t + t + t + t + t + t def t5(): arr = ['text'*100] * 10 for _ in range(1000): s = ''.join(arr) def t6(): for _ in range(1000): s = 'text'*100 + 'text'*100 + ... # всего 10 раз >>> timeit(t4, number=10000) 12.795130728000004 >>> timeit(t5, number=10000) 2.642637542999182 >>> timeit(t6, number=10000) 0.2184546610005782 Вот, уже другой разговор, сразу видна разница, в среднем в 6 раз. Но погодите, почему последний тест t6() по скорости такой же как и t3()? Ведь строки теперь в 100 раз длиннее! Это вопросы оптимизации кода, какие простые изменения ускоряют или замедляют выполнение программы. Мы столкнулись с примером обхода обращения к переменной. Например, именно так работает директива #define в С++, во время компиляции подставляя значение переменной вместо ссылки на неё. В Python это тоже работает, но часто ли вы сможете встретить такой способ работы со строками? К сожалению, способ почти только теоретический. В целом, тесты показали то, что мы хотели. Делаем выводы самостоятельно. Полный листинг 🌍 #tricks

A few minutes ago I had a networking issue, making my server unreachable for a bit more than 5 minutes. Got that resolved and the services are responsive again. It may have happen that some messages got processed twice in that unstable period, which is due to how telegram sends updates. I appologize for any inconvenience. The server is now back to operating normal. #resolved

Fixed a bug where @RulesRules would hang on processing a special type of message. Should now be responsive again. #update#resolved

A file went missing, so not all code to run was there. Basic operation is back. 19:16 UTC @LangInfoBot is back up. 19:26 UTC @BassBoostBot is back up. Lol, as if anyone missed that bot. 19:34 UTC @bonbot is back up soon. Currently fighting with API rate limiting. 19:37 UTC @travis_cibot is back up. 19:45 UTC and the health checks are all good now. #resolved#update

Everything is back up and running again. With that @RulesRulesBot now finally is on the fast new server. #resolved#RulesRulesBot

The worker node of @JoinCaptchaBot just restarted ungreacefully, in some cases causing up to 6 times the same messages. The good news is, while it happend multiple times in the same second, any missed out kicks were now processed as well (6 times). The issue has been identified and will be resolved soon. Sorry for your inconvinience. #resolved#JoinCaptchaBot

@BanWarnBot is nowsuccessfully back up and running the newest version: Here's a list of what's new: New /kick and /ban commands: Just like the /warn one, but immediately removes the user from the chat, either once or permanently. You can specify a reason for why you kicked/banned someone after the command. Those kicks count into the normal warn count, because they are kinda like special warns. Those 3 commands, /warn, /kick and /ban now also allow the first thing after the command to be the id of a user, in the format of #1234, or a user mention. This can come in handy if you don't have a message to reply to. Overhaul of the warning lists: Now the list of /listwarnings and /listallwarnings will link you to the message warn message, if you press the date stamp. Also support for distinguishing automatic kicks/bans and manual kicks/bans has been added. #update#BanWarnBot#resolved

Updated @HeyAdminBot: - Improved handling of private groups, will now export the join link if the bot has the rights for that - Added a direct link to the message ("requested") - Randomizing order of admins called so it's not always the same one being the first to respond. - Fixed bug where the first admin would receive the messages meant for the other admins as well. #update#resolved#HeyAdminBot
