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

🌎 In the Himalayas, the snow leopard’s wide, fur-covered paws act like natural snowshoes, distributing weight and keeping it from sinking on deep mountain snow. ✨ #wildlife⚡#adaptation⚡#Himalayas 👉subscribe Interesting Planet

🌎 The larva of the Himalayan glacier midge survives temperatures as low as -17°C by producing special proteins that act like antifreeze, preventing ice crystals from damaging its tissues. This adaptation lets it thrive in some of the coldest, highest places on Earth. ✨ #insects⚡#adaptation⚡#Himalayas 👉subscribe Interesting Planet

🌎 Bar-headed geese cross the Himalayas during migration, flying at altitudes above 7,000 meters. These birds have special hemoglobin that helps them absorb oxygen efficiently in thin air. Their migration route includes nonstop flights of up to 1,600 kilometers. ✨ #migration⚡#birds⚡#Himalayas 👉subscribe Interesting Planet 👉more Channels ​

🌎 In the soaring skies of the Himalayas, the bar-headed goose migrates over Mount Everest, flying at altitudes above 8,000 meters—higher than any other bird. Special hemoglobin in their blood enables them to absorb oxygen efficiently in the thin air, making this epic journey possible each year. ✨ #migration⚡#birds⚡#Himalayas 👉subscribe Interesting Planet

🌎 Mount Everest's border runs exactly along the Nepal-China divide, making its summit shared by two countries. Hikers can reach the top from either side, but the official border marker is a small metal pole embedded in the ice at 8,848 meters—the highest international boundary on Earth. ✨ #borders⚡#geography⚡#Himalayas 👉subscribe Interesting Planet 👉more Channels ​

🌎 Some Himalayan glaciers are “surge glaciers,” moving up to 100 times faster than normal for short periods. These icy rivers can suddenly speed up, advancing kilometers in months instead of centuries—reshaping valleys with astonishing power. ✨ #glacier⚡#Himalayas⚡#earth 👉subscribe Interesting Planet
