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.

Despite $LIT continuing to drop, a whale has deposited $10M $USDC into #Lighter and is hedging on it. The whale opened a $LIT short position with 5x leverage and spent $2.2M to buy 1.059M $LIT at $2.08 on spot and still holds $2.788M $USDC and is likely to buy more. https://app.lighter.xyz/explorer/accounts/0x2261207edc313bBFe96ddb98618b87919b9F1AeF https://x.com/OnchainLens/status/2010947308557660544 Follow @onchainlens for more onchain updates

Since Telegram announced #Lighter integration in its app, a #Hyperliquid whale didn’t wait. He dumped 12.2K $HYPE ($449.1K), placed another 10.4K $HYPE ($386K) as a sell order, and withdrew $1.26M $USDC today. Notably, he had already closed his multi-million dollar $HYPE longs right after the April 3 announcement. Lifetime PnL: $1.72M+ Does he know something we don’t, or is this just another wrong FOMO trade? https://app.coinmarketman.com/hypertracker/wallet/0x89abe626dc7f010138bc08e0100f1e4e13c30d32 https://x.com/OnchainLens/status/2041344975301190049 Follow @onchainlens for more onchain updates
