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

🌎 Multiple theories in modern physics suggest parallel worlds or dimensions could exist, but no direct experimental evidence has ever been found. String theory predicts extra spatial dimensions, and some cosmological models propose the idea of a "multiverse," where many universes exist with different physical laws. As of 2024, all searches for measurable proof—such as deviations in gravity or missing energy—have reported no confirmed signs of parallel worlds. ✨ #physics⚡#multiverse⚡#cosmology 👉subscribe Interesting Planet 👉more Channels ​

🌎 In physics, the concept of a "multiverse" proposes that our universe could be just one of many coexisting universes, each with different physical laws. This idea arises in cosmic inflation theory, where rapid early expansion could have created countless separate "bubble universes." The multiverse hypothesis is explored by leading scientists but remains unproven, and no direct evidence has yet been observed. ✨ #multiverse⚡#cosmology⚡#physics 👉subscribe Interesting Planet 👉more Channels ​

🌎 The "string theory landscape" in physics proposes that more than 10^500 possible universes, each with different physical laws, could exist within higher-dimensional space. This idea stems from mathematical solutions to string theory equations, where our universe is just one possibility in a vast "multiverse" of parallel worlds. ✨ #physics⚡#multiverse⚡#stringtheory 👉subscribe Interesting Planet 👉more Channels ​

🌎 Scientists exploring the mysteries of parallel worlds suggest that, according to quantum mechanics, alternate dimensions could exist alongside our own—each with its unique version of reality. Though unproven, this idea helps explain puzzling phenomena in physics and inspires everything from science fiction to cutting-edge research about the nature of our universe. ✨ #physics⚡#quantum⚡#multiverse 👉subscribe Interesting Planet ​

🌎 The "brane multiverse" is a scientific idea suggesting our universe might be a three-dimensional "brane" floating in higher-dimensional space. Some versions of string theory propose multiple branes could exist close together, and rare collisions might even trigger new big bangs. The concept arises from efforts to unify gravity with quantum physics. ✨ #multiverse⚡#dimensions⚡#stringtheory 👉subscribe Interesting Planet ​

🌎 Quantum physics allows for the concept of “superposition,” where particles exist in multiple states at once. This principle forms the basis for theories suggesting that parallel worlds or dimensions might exist alongside our own. The famous “double-slit experiment” demonstrates superposition, as particles act as if they travel through two paths simultaneously. ✨ #quantum⚡#superposition⚡#multiverse 👉subscribe Interesting Planet 👉more Channels ​

🌎 The concept of parallel worlds is grounded in the "many-worlds interpretation" of quantum mechanics, proposed by physicist Hugh Everett in 1957. It suggests every quantum event may split reality into new branches, creating countless coexisting universes. Unlike science fiction, this idea remains unproven and is debated among physicists, but it offers possible explanations for phenomena like quantum superposition. ✨ #quantum⚡#physics⚡#multiverse⚡#science 👉subscribe Interesting Planet ​
