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

🚀 Abraxas Capital's Oil Short Positions Recover Following Ceasefire Announcement On April 9, Hyperinsight reported significant financial recovery for Abraxas Capital, a major oil short institution on the Hyperliquid platform. According to BlockBeats, the recovery occurred within a week following the announcement of a ceasefire, with funds rebounding by over $12 million. The combination of oil shorts and crypto longs, which previously faced a floating loss of $9.7 million, has now turned profitable. As of the latest update, the two addresses continue to synchronize profit-taking and position reduction, maintaining a floating profit of $8.7 million. Following the recent reduction in positions, the total holding size remains at $152 million. This includes approximately $126 million in short positions on U.S. and Brent crude oil, and $26.1 million in long positions in the crypto market. Details of the oil short positions are as follows: Brent Oil shorts (5x leverage) have decreased from $92 million to $78 million, with an average price of around $96. WTI Crude shorts (5x leverage) have reduced from $51 million to $48.5 million, with an average price of approximately $95. Addresses involved are 0x5b5d51203a0f9079f8aeb098a6523a13F298C060 and 0xb83de012dba672c76a7dbbbf3e459cb59d7d6e36. #AbraxasCapital#OilShortPositions#CeasefireAnnouncement#FinancialRecovery#Hyperinsight#BlockBeats#CryptoLongs#ProfitTaking#WTICrude#BrentOil#OilMarket#LeverageTrading#PositionReduction#FloatingProfit#CryptoMarket#U.S.Crude
