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

🚀 Bitcoin Futures Open Interest Hits 14-Month Low Amid Institutional Strategy Shift On April 11, the open interest in Chicago Mercantile Exchange (CME) Bitcoin futures fell to $8.41 billion, marking its lowest level in 14 months. According to BlockBeats, Glassnode analysts attribute this decline primarily to the unwinding of basis trades. Previously, this strategy involved establishing long positions through spot ETFs and hedging with short futures to earn the spread. However, the annualized returns have recently dropped from 15%-20% to around 5%, prompting institutions to take profits. Additionally, the daily trading volume of CME Bitcoin futures has decreased to below $3 billion. Analysts suggest that as institutional demand shifts towards directly holding spot assets, the leverage in the futures market is significantly decreasing. #BitcoinFutures#OpenInterest#CME#BasisTrades#InstitutionalStrategy#SpotETFs#FuturesMarket#Leverage#TradingVolume#BlockBeats#Glassnode#CryptoMarket#BTC
