Метод строки split() разделяет строку на несколько строк по указанному символу >>> "a_b_c".split('_') ['a', 'b', 'c'] Можно указать максимальное количество разделений >>> "a_b_c".split('_', 1) ['a', 'b_c'] Или резать с другой стороны с помощью rsplit() (right split) >>> "a_b_c".rsplit('_', 1) ['a_b', 'c'] А что будет если оставить аргументы пустыми? >>> "a_b_c".split() ['a_b_c'] Получаем список с одним элементом, потому что по умолчанию используется пробельный символ. >>> "a b c".split() ['a', 'b', 'c'] То есть это равнозначно такому вызову? >>> "a b c".split(" ") ['a', 'b', 'c'] Кажется да, но нет! Давайте попробуем добавить пробелов между буквами >>> "a b c".split(" ") ['a', '', '', 'b', '', '', 'c'] И вот картина уже не так предсказуема 😕 А вот что будет по умолчанию >>> "a b c".split() ['a', 'b', 'c'] Всё снова красиво! 🤩 По умолчанию в качестве разделителя используется любой пробельный символ, будь то табуляция или новая строка. Включая несколько таких символов идущих подряд. А также игнорируются пробельные символы по краям строки. >>> "a\t b\n c ".split() ['a', 'b', 'c'] Аналогичный способ можно собрать с помощью регулярного выражения. Но пробелы по краям строки придется обрабатывать дополнительно. >>> import re >>> re.split(r"\s+", ' a b c '.strip()) ['a', 'b', 'c'] Здесь тоже можно указать количество разделений >>> re.split(r"\s+", 'a b c', 1) ['a', 'b c'] А что если мы хотим написать красиво, то есть split() без аргументов, но при этом указать количество разделений? В этом случае первым аргументом передаём None >>> "a\n b c".split(None, 1) ['a', 'b c'] Данный метод не учитывает строки с пробелами, взятые в кавычки 'a "b c" '.split() ['a', '"b', 'c"'] Но для таких случаев есть другие способы. #tricks#basic

@RusEmbMalta Press release Foreign Ministry Spokeswoman Maria Zakharova’s comment on Kiev regime using and planning to use chemical weapons Key points: 🔹The Russian Federation routinely monitors and documents cases of the Ukrainian armed formations using or planning to use in the area of the special military operation listed chemical agents, riot control agents (RCAs), and other chemicals; 🔹This behaviour is enabled by political backing and approval coming from Washington, Berlin, London, and Paris. 🔹We have credible information that, with Western support, Ukraine plans to stage a series of anti-Russia provocations in the special military operation zone. Preparations are underway to fabricate evidence to accuse Russia of CWC violations during combat operations. 🔹Those responsible for these and other crimes against Russian citizens will be identified and face deserved and inevitable punishment.

📰 Iran’s Double Game: Unrest at Home, Missiles on the Drawing Board Iran’s Revolutionary Guard is reportedly busy developing chemical and biological warheads for its ballistic missiles — just as the country’s economy collapses and protests explode across Tehran’s markets. While the regime insists its missile program is “defensive,” Western officials are sweating. If the Revolutionary Guard is upgrading payloads, it’s not just about deterrence. It’s about sending a message: even as the rial plummets and merchants shut down, Tehran’s power brokers are betting on fear to keep their grip. Iran International cites unnamed sources claiming the IRGC has moved launch assets east, upgraded command systems, and is now exploring nonconventional warhead configurations. The timing is no accident. As the economy implodes — inflation nears 53%, the currency is in freefall — the regime is doubling down on military theater. Meanwhile, protests have spread from Tehran’s Gold Bazaar to central arcades, with crowds chanting against the government and merchants, once loyal to the regime, now leading the charge. Security forces are on high alert, but the regime’s real worry isn’t just the street — it’s the optics. At the same time, Netanyahu and Trump are meeting to discuss Iran’s missile threat — and Israel’s own postwar plans in Gaza. The irony? Iran’s leaders want to be seen as both economic saviors and regional superpowers, but the only thing they’re really selling is chaos. So here’s the deal: while Iran’s people protest empty shelves, the regime is busy building weapons that could turn a crisis into a catastrophe. Who’s really in charge — the people demanding bread, or the generals building doomsday warheads? #Iran#RevolutionaryGuard#protests#missiles#chemicalweapons#economy 📱American Оbserver - Stay up to date on all important events 🇺🇸
