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

📕💬Полёт по кругу («полёт по коробочке») — полёт по установленному маршруту (обычно прямоугольному) в районе аэродрома для выполнения взлёта, захода на посадку и посадки, а также для ухода и подхода к аэродрому. Является важной частью захода на посадку и УТП (учебно-тренировочных полётов) на самолётах и планёрах. В случае УТП на самолёте может применяться посадка конвейером Лёгкое небо #c172#flight#vfr

Witkoff and Kushner: Flight Canceled ✈️❌ Trump canceled the trip by his envoys Witkoff and Kushner to Islamabad due to the Iranian position in peace negotiations. 🇮🇷🤝🚫 The envoys had been expected to meet with Iranian Foreign Minister Araghchi, in a trip designed to break a diplomatic stalemate and build momentum for a deal. I see no point of sending them on an 18-hour flight in the current situation [of the negotiations]. It's too long. We can do it just as well by telephone. 📞 Asked whether it means he is going to resume the war, Trump said: "No. It doesn't mean that. We haven't thought about it yet." ⚔️🚫 "We have all the cards. We are not going to go there to sit around talking about nothing." 🃏 Trump later told reporters Saturday afternoon that the meeting with the Iranians wasn't going to happen until Tuesday, and that therefore he thought it was a waste of time to travel to Pakistan. 🕰 He also said a counteroffer Araghchi gave the Pakistanis on Saturday wasn't good enough. 📄🚫 "They gave us a paper that should have been better and interestingly the minute I cancelled it, within 10 minutes, we got a new paper that was much better (…) they offered a lot but not enough," Trump said. ⏱️📝 While Trump extended the ceasefire with Iran earlier this week, the diplomatic efforts haven't made any progress in recent days. 🕊⏸️ U.S. officials had said Iran's divided factions had a short window to come together on an offer. 🪟👥 "There is tremendous infighting and confusion within their 'leadership.' Nobody knows who is in charge, including them," Trump said in a Truth Social post Saturday after calling off the trip. 😵‍💫📢 Araghchi met on Saturday in Islamabad with Pakistan's prime minister, army commander, and foreign minister, who have been mediating between the sides. 🇵🇰🤝 But the talks ended with no significant progress. Araghchi left Islamabad without committing to meet Witkoff and Kushner if they traveled to Pakistan. 🚶‍♂️🚫 The Iranian foreign minister expressed in his meetings that Iran demands the lifting of the U.S. naval blockade as a pre-condition for talks. ⚓️🚫 About an hour after Araghchi left Islamabad, Trump decided to cancel the trip. ⏳❌ "Have yet to see if the U.S. is truly serious about diplomacy," Araghchi said in a post on X thanking the Pakistanis for their efforts. 🤔🇺🇸 What comes next isn't clear, though Trump allies called on the president to continue pressure on the Iranians — even if that means resuming military operations. 🤷‍♂️🔥 #witkoff#kushner#araghchi#trump#flight 📱American Оbserver - Stay up to date on all important events 🇺🇸
