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

​Now is the time and we are building!💎 The Open Network (TON) is growing strong developer communities in countries across the globe as our Hackathon provides developers with the necessary resources and guidance to build something incredible.🔥 Super excited to announce our INVITE-ONLY, on-site events. During our Hackathon this February, we will invite 6~10 teams that are looking to #buidl on #TON in a city that could be near you! Our goal is to empower builders and developers in local communities to create innovative applications, services and protocols with The Open Network. For the event, builders and developers will get a chance to meet and ask questions to a member of The TON Foundation and local TON developer specialist(s). The Q&A session will ensure that builders and developers are well equipped with knowledge about TON tools, incubation opportunities and building on TON mainnet. Join us on our mission to unite all blockchains and Web2 internet into one open network! If you want to attend and are excited to #BuildOnTon, please submit an introduction and your BUIDL idea! 🤓💻 To be eligible to WIN exclusive access, please abide by the following criteria: - Max. two people per team - Max. 150~250 words per pitch - Keep it concise and clear - Focus on value for the TON community - Submission period: Jan 18 (Wed) ~ Jan 25 (Wed) We are super keen to have developers from all over the world join us on our mission to build the next-gen internet.
