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

🚀 Binance to Launch RateX Trading Competition with Token Rewards According to the announcement from Binance, the platform is set to introduce the RateX Trading Competition on Binance Alpha. This event will take place over two distinct promotion periods, offering participants the opportunity to earn exclusive token rewards. The first promotion period is scheduled from 2026-04-09 13:00 (UTC) to 2026-04-16 13:00 (UTC), followed by the second from 2026-04-16 13:00 (UTC) to 2026-04-23 13:00 (UTC). Participants will be ranked based on their total purchase volume of RateX (RTX) tokens during each period. The top 2,040 users in each period will share a pool of 61,200 RTX tokens, with each eligible participant receiving 30 RTX tokens. Participation in the competition requires trading through Binance Wallet (Keyless) or Binance Alpha, as third-party dApp transactions are excluded. Only cumulative purchases will count, with no volume caps imposed on participants. However, token bridging transactions are not eligible. Notably, trading volume from Alpha-to-Alpha token pairs will not contribute to Alpha Points or competition rankings, effective from 2025-06-17 00:00 (UTC). Rewards will be distributed in RTX tokens and must be claimed by eligible users before 2026-05-07 13:00:00 (UTC). Unclaimed rewards within 14 days will be forfeited. To participate, users must click 'Join' on the Binance App event page, ensuring their trading volume is counted. The latest version of the Binance App and a backed-up Binance Wallet (Keyless) are required. Rankings will be calculated automatically post-promotion, and winners can claim rewards via their Binance Alpha accounts or Binance Wallet (Keyless). Binance reserves the right to amend the terms of the competition at its discretion. #Binance#RateX#TradingCompetition#TokenRewards#CryptoEvent#BinanceAlpha#RTX#TokenDistribution#BinanceWallet#TradingVolume#CryptoPromotion#TokenBridging#CompetitionRanking#AlphaPoints#BinanceApp#Keyless
