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

🚘 Cybercab announced: Elon Musk’s robotaxi is finally here 📍 Tesla boss Elon Musk has unveiled the firm's long-awaited robotaxi, the Cybercab, at the Warner Bros Studios in Burbank, California. 🚕 The robotaxi is a purpose-built autonomous vehicle, lacking a steering wheel or pedals, meaning it will need approval from regulators before going into production. The design was futuristic, with doors that open upward like butterfly wings and a small cabin with only enough space for two passengers. There was no steering wheel or pedals, nor was there a plug — Musk said the vehicle charges inductively to regain power wirelessly. 🚐 In a surprise, the company also revealed a "robovan," a self-driving van capable of carrying up to 20 passengers or being configured for cargo purposes. 🪙 Musk said that autonomous cars are expected to be 10–20 times safer than human-driven vehicles and could cost as little as 20 cents per mile, compared to the $1 per mile for city buses. @CarsNews #Tesla#driverless

New 🚘 electric cars will get Chinese autopilot It will be developed by startup Momenta and will debut on the CLA electric sedan. The hardware will be based on Nvidia's Orin X chip. The all-electric CLA will be equipped with a high-level intelligent driving system that does not rely on high-definition maps. This advanced system will provide navigation in the city, and mass production of the electric car is scheduled for April 2025. Mercedes-Benz is one of Momenta's investors, along with GM and SAIC. @CarsNews #Mercedes#EV#driverless

🚕Waymo robotaxis are back at the center of a scandal 📍 This time, the vehicles caused chaos on the streets of San Francisco. 🚥 The autonomous taxis use the traffic-light system for navigation, so when it goes down, route planning breaks as well. ⛔ For several hours, Waymo cars stood on the roads like bricks, blocking other drivers from getting through. Is rise of the the machines beginning? #driverless#incidents@Car_News

😰Three Waymo robotaxis caused a “standoff” and blocked a street in San Francisco 📰 In the northern part of San Francisco, three Waymo autonomous taxis got stuck on a narrow street, completely blocking traffic. Two cars lightly collided while trying to maneuver, after which both went into emergency mode, and the third stopped right in front of them, creating a full traffic jam. 😤 Because of this, residents couldn’t leave their driveways and had to wait for company engineers to intervene and resolve the situation. All vehicles were empty — no passengers were inside. 💬 Waymo commented on the incident, calling it a “learning moment” for improving their autonomous driving system. #driverless#incidents@Car_News
