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

🌎 The rare blue mineral painite was first discovered in Myanmar in 1951 and is so scarce that only a few hundred crystals have ever been found worldwide. Painite contains boron, zirconium, and aluminum, and transparent gem-quality stones are especially valuable to collectors. ✨ #geology⚡#minerals⚡#gemstones 👉subscribe Interesting Planet 👉more Channels ​

🌎 Red beryl, also called bixbite, is one of the rarest gemstones on Earth and is found almost exclusively in Utah’s Wah Wah Mountains. Its rich red color comes from trace amounts of manganese. Fewer than one red beryl is found for every 150,000 diamonds mined worldwide. ✨ #minerals⚡#gemstones⚡#geology 👉subscribe Interesting Planet 👉more Channels ​

🌎 Discovered only in Greenland and the Kola Peninsula, rare mineral serendibite forms deep in metamorphic rocks and can display vivid blue-green hues. Gem-quality serendibite is so scarce that a single carat can cost over $2,000. ✨ #minerals⚡#geology⚡#gemstones 👉subscribe Interesting Planet 👉more Channels ​

🌎 Blue garnet is one of the rarest gemstones on Earth, discovered in Madagascar in the late 1990s. Unlike most garnets, it changes color—from blue-green in daylight to purple-red under incandescent light—due to trace amounts of vanadium absorbing light differently. Only tiny amounts have been found so far, with most crystals under one carat. ✨ #geology⚡#minerals⚡#gemstones 👉subscribe Interesting Planet 👉more Channels ​

🌎 The mineral grandidierite is one of the world’s rarest gemstones and was first discovered in Madagascar in 1902. Its blue-green crystals get their striking color from traces of iron, and transparent gem-quality stones are so scarce that most museums only display tiny specimens. ✨ #minerals⚡#gemstones⚡#geology 👉subscribe Interesting Planet ​

🌎 The mineral taaffeite was discovered accidentally in 1945 by gemologist Richard Taaffe, who bought a mislabeled gemstone in Dublin. This rare crystal is prized for its lavender color and is mostly found in Sri Lanka, Myanmar, and Madagascar. Fewer than 50 verified cut taaffeites exist worldwide. ✨ #minerals⚡#gemstones⚡#geology 👉subscribe Interesting Planet ​

🌎 In Australia’s opal fields, some opals contain ancient fossilized bones or shells, perfectly preserved in dazzling rainbow stone. This rare “opalized fossil” forms as minerals slowly replace bone, creating a sparkling record of prehistoric life. ✨ #fossils⚡#minerals⚡#gemstones 👉subscribe Interesting Planet

🌎 The mineral jeremejevite forms pale blue, yellow, or colorless crystals and is among the world’s rarest minerals. Discovered in Namibia in 1883, it is an aluminum borate mineral that forms in granite pegmatites. Transparent gem-quality jeremejevite is so scarce that it can sell for over $2,000 per carat. ✨ #minerals⚡#crystals⚡#gemstones 👉subscribe Interesting Planet ​

🌎 Alexandrite is a rare mineral that changes color under different lighting—appearing green in daylight and red under incandescent light. This gemstone was first discovered in Russia’s Ural Mountains in 1830, and crystals large enough for jewelry are extremely scarce worldwide. ✨ #alexandrite⚡#minerals⚡#gemstones 👉subscribe Interesting Planet 👉more Channels ​
