Скорее всего уже слышали, что складывать строки через + это плохая практика. Падение производительности, и всё такое. Без лишних слов, давайте измерять: from timeit import timeit def t1(): # складываем 10 строк через + из переменной t = 'text' for _ in range(1000): s = t + t + t + t + t + t + t + t + t def t2(): # склеиваем список строк через метод join arr = ['text'] * 10 for _ in range(1000): s = ''.join(arr) def t3(): # складываем через + но не из переменной а непосредственно инлайн объекты for _ in range(1000): s = 'text' + 'text' + 'text' + ... # всего 10 раз Теперь каждую строку склейки запустим по 10М раз >>> timeit(t1, number=10000) 0.21951690399964718 >>> timeit(t2, number=10000) 1.4978306379998685 >>> timeit(t3, number=10000) 0.2213820789993406 Хм, а нам говорили что через "+" это плохо и медленно ))) 😁 Тут стоит учитывать, что речь идёт о склейке множества длинных строк. Давайте изменим условия: def t4(): t = 'text'*100 for _ in range(1000): s = t + t + t + t + t + t + t + t + t def t5(): arr = ['text'*100] * 10 for _ in range(1000): s = ''.join(arr) def t6(): for _ in range(1000): s = 'text'*100 + 'text'*100 + ... # всего 10 раз >>> timeit(t4, number=10000) 12.795130728000004 >>> timeit(t5, number=10000) 2.642637542999182 >>> timeit(t6, number=10000) 0.2184546610005782 Вот, уже другой разговор, сразу видна разница, в среднем в 6 раз. Но погодите, почему последний тест t6() по скорости такой же как и t3()? Ведь строки теперь в 100 раз длиннее! Это вопросы оптимизации кода, какие простые изменения ускоряют или замедляют выполнение программы. Мы столкнулись с примером обхода обращения к переменной. Например, именно так работает директива #define в С++, во время компиляции подставляя значение переменной вместо ссылки на неё. В Python это тоже работает, но часто ли вы сможете встретить такой способ работы со строками? К сожалению, способ почти только теоретический. В целом, тесты показали то, что мы хотели. Делаем выводы самостоятельно. Полный листинг 🌍 #tricks

Do Kwon Extradited to the USA Montenegro's Justice Minister Bojan Bozovic has ordered the extradition of Do Kwon, founder of Terra, to the United States. This comes after the court denied Kwon's appeal against extradition. Kwon remains under scrutiny for alleged fraud amounting to $4.47 billion, and was arrested in March 2023. His extradition allows U.S. authorities to pursue charges related to investor deception and wealth concealment.

Cuban Prefers Bitcoin Over Gold in Crisis Billionaire Mark Cuban states he prefers holding Bitcoin over gold in economic downturns, citing higher value potential. In Q4 2024, MicroStrategy purchased 194,180 BTC. Companies like KULR Technology, Rumble, and Genius Group are also adding Bitcoin to their balance sheets. Meanwhile, Do Kwon faces trial in 2026 for TerraUSD's $40 billion collapse. Additionally, 50 million USDC was burned at USDC Treasury. Analysts from Fidelity Digital Assets predict significant Bitcoin growth in 2025, potentially driven by countries accumulating Bitcoin as strategic reserves. #Bitcoin#Crypto#VC#MarkCuban#MicroStrategy#KULR#Rumble#GeniusGroup#DoKwon#TerraUSD#USDC#Fidelity#ETB#DigitalAssets#EconomicCrisis#Forecast#Cryptocurrency
