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

Why am i so addled, i seek retort through this creation. Can't understand a thing, anymore. I just need Salvation What am i gonna gain, if anything, why do i need revelation. I do just fine without mass, getting back to isolation? Why is it so important, why look for identification? Is it the curiosity or the fear of seperation? There is inspiration, there is recreation, there is manipulation, sensation, violation & frustration but is there anything that's necessary? Is there any elevation? I know it bothers none but please, tell me, where am i heading to, what is my destination? #Snowy#review

I mutilate myself, no matter what i do. Acting all spirit, i maim when I'm disregarded, when I'm passed over. Acting all foul isn't my cup of tea either, i maim again, i incapacitate either way. Being ignoble and or moral, both roads are noxious to me. What do i fancy then? You blemish me, your bygones. I can't condone it. I can't strand you either. You, your, it impedes me, candidly but won't gash you by disclaim, renounce.... Won't? Well, can't is more apt, can't bestow to soar your agony.... But about my torment? I have nowhere to go, no door left open, I'm stuck, stuck with you. I'll dwell, I'll persist, that's what I've been doing, that's what i can keep up with. No possibility, either at whim or reluctantly, i have to adhere, no recourse.... I'd be thrusting here, i don't know the stretch, the extent, maybe perpetuity. #review#Snowy

You were fire, i wasn't ice I was supposed to but it wasn't nice I was magma that was piquant Why was our bond so highly turbulent? The violent gesticulation of air around your flames Wasn't any good for my fever but i got used to the games We were bonded the way we weren't meant to be Was it destiny, i wondered or was it our will that was the key You're no good for me, i know, said she But it was too late for her to be set in the world again like a bird, free If we're meant to do it together, yes my love, we suffer like the way we suffered You'd be the flame of my candle that demolishes my wax, he uttered Afterall, diamonds dice diamonds, they are suited together Shouldn't be befuddled with types different but stay where they belong, forever #Snowy #review
