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

🚀 Middle East Ceasefire Expected to Hold Despite Fragility Jefferies global economist Mohit Kumar has stated that despite the fragility of the Middle East ceasefire agreement, it is expected to hold. According to Odaily, Kumar noted that both parties have reached a point where they desire a ceasefire, as continued conflict would negatively impact both sides. Kumar highlighted that U.S. President Donald Trump is keen on reaching an agreement, as he lacks support from his core base for ongoing warfare. Meanwhile, the Iranian Revolutionary Guard faces challenges due to economic devastation, potentially paving the way for future uprisings. He concluded that given the interests of both parties, the unstable ceasefire is likely to persist. #MiddleEast#Ceasefire#MohitKumar#US#Iran#DonaldTrump#Conflict#RevolutionaryGuard#GlobalEconomics#PeaceAgreement#Odaily

🚀 WLFI Co-Founder Addresses Misunderstandings on X Platform WLFI co-founder Zach Witkoff has responded to recent criticisms on the X platform regarding the WLFI project. According to Odaily, Witkoff clarified several points to address misconceptions. Firstly, he emphasized that WLFI should not be confused with the Trump meme coin, as they are entirely unrelated. He also stated that WLFI has no connection with 'fight fight fight' or CIC Digital Company. Witkoff highlighted that early investors purchased WLFI at prices of $0.015 and $0.05, with the current price standing at $0.08. He further explained that the project's primary product is not transaction fees but a stablecoin that generates returns through holding government bonds. This stablecoin ranks as the second-largest compliant stablecoin by trading volume and market capitalization, which he described as a significant achievement. Witkoff advised critics to conduct more thorough research before writing extensive posts on the matter. #WLFI#ZachWitkoff#XPlatform#TrumpMemeCoin#Stablecoin#GovernmentBonds#Investors#Misunderstandings#CICDigitalCompany#Cryptocurrency#Odaily#MarketCapitalization
